@@brentmeredith5295 Yessir. People posting stuff for views but passing on bad data is crap.

No, the 351m -400m shared the 460 bell housing pattern! They were both dogs, especially the 351m! I had one in a 77 Thunderbird! 15mpg, up hill, downhill, didn't matter! By the time you put any M motor in it, you should've put a 460 in it! There were millions of F150's with these motors! The 351m was a boat anchor! Shoulda just put the 400m in it! If you were really working it, a 460!! All the "M" motors were bastards! They oiled the top end of the motor before they oiled the crank! The only good thing about a 400m is a 460 would bolt to the bellhousing! For most people, the 351w had enough to get by, and still a daily driver! I pulled a 6300lb camper with a 351w!! Most of you people didn't work them! Pulled a 22' trailer decked with 1/8" cold roll with a bobcat and all the supplies for a day to the job sight! 5 years!

@@markmccarty9793 Easy with the exclamation marks hero, it's not that exciting of a topic. I said what you said. Reread it. I clearly stated that the 351C shared the same bell as the Windsors. There is also no such thing as a 400M. It was 351C, 351M and 400. And saying things like, "most of you people...." and assuming anything about any of us here is plain condescending. You don't know anyone in the comment section so get off your high-horse. If you wantbl to correct someone, correct them when they are wrong instead of reiterating what they said with similar wording. Also learn the nomenclature. Here is a good example of when to use an exclamation point and how to properly be condescending: "A 400M.... good lord!.....

I can see that you aren't intelligent enough to hit spell check! The 351m, 400m, 429, 460 shared the same bellhousing patterns, as well as gas milage! Start taking prevagen now, you're gonna need it!

I’d rather have the Windsor engine over the Cleveland engine. For if anything, ease of modifying, parts availability and so on. However, if you do some research you can make improvements to it to work better.

GTHOs did not have Aussie Cleveland's , our Cleveland production started in 1974 , and all Aussie Clevelands use 2V ports , even though they were 4 barrels , the 351 C in the GTHO 2 1/2 s and lll s were 4V US Boss 351s , we didn't start casting at the Geelong Casting Centre untill late 1973/4 . When US production stopped .

Also installed in a Ute, which is basically like a Ranchero. A tire shredder.

Fastest in Australia 140 mph..dodge polara chp 1969 ..149 mph

Hmmm, Ford in America built the Ph3 Clevo rated at 300hp. 380 is an educated guess on what they should be. 161 mph? in your dreams. Knock of 20mph and that is about it. Still very fast. 161 hp.. need 500+ hp to go that fast. Racecars do it but not stock HO motors

But there's alota deck there, and plenty room for a good long rod! The 400m did a good job, but that oiling priority was screwed up! You need to keep the oil primarily to the crank! Had both, the 351m and the 400! The 400 was a mule!.but, by that time you sholda had a 460! Emissions screwed us on that! Ran a cheap 460 for a while in a Mustang. But buy the time you got all thar rotating turning you still had the extra 300 lbs or so to haul! But, 460's were cheap, dependable, available down here! Save up a little and build a 408 Windsor! Shoot a 100-150 shot and back the timing, 2-3 degrees for every 50hp. Don't turn it past bout 6500, change the oil out every 5-6 weeks! It'll run forever, but don't worry if you lose! I didn't drive, but looked at the slips, took note of the temperature, 60' and trap speed. Even a castpiston (we used Speed Pro cast pistons in the 1st motor)! Windsosr will live if you just take care of them, don't waste your time and money on a 306!

That's a good way of putting it. It's all about that torque.

ALL Cleveland and M engines have the same poor oiling. 302-400. Modern synthetic oil helps them but they are at best a heavy gunker!! I have a 400M in my Galaxie. Near stock and reliable, I had a 351C in my Falcon racecar, that is being replaced with a 347 with 3V CHI alloy heads. I can turn that a 1000 rpm higher and it will stay together.

I cam here to say just this plus some other things; because, then folks at CJ obviously don’t know what deck height actually is and how it’s measured, along within many other things about these engines.

​@backinblck1 definitely some truth there. At 2:40 when talking about deck height, they are showing a measured height going to the top center from crankshaft position. Deck height is measured from crank center line to top of block where head mounts ( not where intake mounts as shown here).

@@BS-Outdoors1320 Guy, the original "boss 302" is a Windsor block with cleveland heads, the cleveland was available in Aussie as a 302 2V with closed chamber heads and a 351 2V with open chamber heads, same block different crank and rods to make the 302C in Aussie. It was not available in the US with only the 351 2V (standard valves/ports) or 351 4V, bigger valves/ports) 351C 4V was also available in Aussie in GTs from XY through to XB, post XB were all 2V in either 302C or 351C. Windsor 302 was phased out when the cleveland entered in 1969/70 however with the demise of the cleveland at the end of the XE Falcon around 1984 , the 302 Windsor reappeared from EB Falcon in 1992 through to AU Falcon 2002/03 where it was replaced by the 5.4 OHC in 3 valve AND 4 valve in BA-FG Falcon models before itself being replaced with the Coyote 5.0 N/A and the Miami 5.0 supercharged.

@@whakatu4life285 I was assuming you had an actual " boss 302" not a destroked 351 Cleveland.

I seriously doubt that bs! The 351w had been around since 69! The 351w has the same bore spacing, same bell housing, motor mounts as the small blocks, as well for the Cleveland bell housing! The 351m was a bastard with the same bell housing as the 400m-460. The 351m-400m were in Ford pickups and cars, including I had one! They were gas hogs, but had great midrange torque, hence the truck applications. Ran all of them over the years, with good results, with the exception of fuel economy! The M motors have great torque, but you pay for it! The 351w is a great compromise!

@markmccarty9793 Apperently you didn't read what I wrote. Ford never stopped production of 351W's in 75, they just had an issue in keeping up with demand. That is where the 351M comes in. Ford initially built them to supplement the demand for 351's at the time, both the W and M engine was available at the same time. Eventually the bad block issue was resolved but Ford kept building the M until 79. I had one in a 78 t bird

I've heard this elsewhere too, Ford couldn't produce enough 351w engines to meet the demand they had for 351 cubic inch motors, so the destroked the 400 to create the 351M

I’ve also herd this!! is was a supply vs demand issue and the 385 bell housing allowed it to drop straight into the f100 line up

Ok, I'll take your word for that! But, I had a 351m in a 78 thunderbird! Now I drove the 302 thunderbird! My grandfather bought one new! Yes, the 351m had good torque! But at a 4 mpg penalty! I've had 400m powered cars, I can only guess that the 351m met the EPA requirements better! The 351m SUCKED! And I'm a Ford guy!

Yes, there was a 221w. I have only ever seen one that was imported into Australia in about 1980 by a friend who was a local sprint car driver and care restorer. I think he ordered a shipping container of assorted Ford motors/parts from the States and it was in that lot. There was also a couple of 260s as well. The 221 and 260 had "slotted heads" for the push rods (acted as guides) and didnt use rail rockers - they used the same rocker arms and hardened push rods as the 289 HiPo. I bought some of this valve gear from him for a 289 I was building at the time because I couldn't afford roller rockers and needed something stronger than rail rockers.

The 221 & 260 came out at the same time, a year or 2 before the 289. I'd guess the 221 was to compete with the GM all aluminum 215 they put in early 60s Olds Cutlases & Pontiac Tempests. The 260/4V was put in the British Sunbeam Tigers before the 289 was offered.

Aw, I think the 221 was actually first and the 260 followed very shortly after. Then the 289 not very long after the 260 as well. 👍

You are correct about the Cleveland heads bolting up to (and obviously working on) Windsor blocks, such as the Boss 302 as you stated. However the Boss 351 IS a Cleveland.. It is not a 351 Windsor with the Cleveland heads, though that would be an interesting engine.

@@purpurahaze9179 Or cut a hole to clear and put a factor hood scoop over it.

351Ws are quite a bit taller & about 4" wider than a 302 so getting it between the inner fenders(part of the chassis structure) might be difficult. Not sure about the Fox but early Falcons(the basic floorpan of the first Mustangs), Fairlanes(67 & earlier) & Mustangs(66 & earlier) would be a very tight fit for a 351 without major mods like Ford subcontracted out to Kar Kraft for the Boss 429 Mustangs. Engine compartments got bigger in the 67-8 Mustangs but ya still had to undo the motor mounts & lift the 390FE engines up a bit to change plugs in them. The LS conversion is very popular for Foxstangs because they're dimensionally smaller.

@@daledavies2334 in the 80's I built a 372 using the 400 crank. The counter weighs were cut down. Notch the block near the oil pump mounting and sides of the pan rails. The front of the crank is different than a Windsor so the gear needs to be modified.

Only because it didn't make enough horsepower to be able to hurt itself.

Peter you obviously know what it takes to make a Ford 400 into a radical performance engine. Unfortunately Ford never even offered a 4 barrel option for the 400 so it never really caught on as a performance engine. I have been involved with drag racing Clevelands for 40 years and I’m familiar with the Hot Rod build of the 400 with 600+ horsepower. Ford designed the 400 to make torque with the longer stroke and more displacement than the 351 so it could be used in their larger sedans and pickup trucks. It worked well for that application. But it’s also a performance engine when the right parts are used. Starting with a pair of Cleveland 4-V closed chamber (quench) heads with upgraded stainless steel valves and single groove keepers for the retainers. The stock 3 groove retainers fail quickly at higher rpm’s. The aftermarket has 4-V aluminum intake manifolds for the taller deck height of the 400. Spacers are also available to use 351C intake manifolds and heads on the 400 block. The Cleveland heads need higher compression to really scream so a set of forged flat top pistons are required for serious power. Naturally a performance cam is required. I use solid roller mechanical cams but a hydraulic roller cam and lifter set would work well on the streets. A 400 cubic inch Cleveland is pretty badass. More displacement works well with the 4-V Cleveland heads and 434 stroker kits are also available. Powerful builds are possible using original Ford production parts. The aftermarket offers Cleveland components from Australia and the States. Aluminum heads, blocks and everything needed to build 1000 horsepower, single 4 barrel, naturally aspirated Cleveland strokers WITHOUT NITROUS 👍. There are several examples here on KZfaq worth checking out. Anyone interested in building Clevelands or seriously powerful 400’s, needs to visit Timothy Meyers website. He’s an expert on all things Cleveland and 335 series Ford engines along with being a master automotive machinist. tmeyerinc.com

Local casting commenced approx 1976 and finished in December 1981. However, the 'Pillow' block Cleveland was cast from Jan to March 1982 and then the XE192540 block was cast from March through to May/June of 1982 - that was the very end of Cleveland engine casting in Australia. Regarding supplies, Ford Aus stockpiled completed 351C engines for use in the Ford F Series vehicles - I saw a photo of this (also available to external companies such as DeTomaso etc). The 7th gen F Series used only the 351C up until August 1985 (you could also get the 4.1L 6 engine as well). Ford Passenger cars were fitted with 302C/351C up until December 1982 (Falcon/Fairmont up to November 1982 and Fairlane/LTD up to December 1982 - Ford Aus released a press bulletin stating that although the silver XE Fairmont Ghia was the last Falcon/Fairmont to be produced with a V8, V8 production for the Fairlane/LTD would continue at the Eagle Farm plant through to December 1982. And yes, I have Ford production records showing 23 5.8 XE Falcons were made in January of 1983 but this was written in as an "extra" so take that with a grain of salt, who knows if it's true or not). From January 1983 on wards it was only the carburetted and EFI 6 cylinder engines that were available for all passenger cars (Falcon, Fairmont, Fairlane, LTD), By 1984 Ford realised that they were running out of the 351C engines (for the F Series vehicles) and thus, the 302W EFI - 5.0Litre, was then brought in (fully imported), and was first seen in F100 Ambulance and Bronco as of January 1985. By September of 1985, everything was 5.0L Windsor EFI in F100 (soon to be F150 as F100 name was dropped) and then same for F250 and F350. By 1987, the F250 and F350 had been dropped from everyday sale and it was only the Ambulance form that the F250 was available in. Come 1990, the 5.8W EFI was introduced and the 5.0W EFI was dropped.

@@davidewhite69 It was a self-fulfilling prophecy. In the late '70's, Ford Aus produced a report showing the % of 4, 6 and 8 cylinder cars. The V8's showed approx 25% (excluding commercial vehicles - utes, panel vans and F Series). That is, the V8 was a popular choice. However, with the introduction of the XD (similar to the VB Commodore), the intent was to achieve weight saving/fuel economy. Ford made a conscious decision to 'go green', read, plastic bumper bars, plastic fuel tanks, alloy head engines (6 cyl) with the desired outcome of being seen to have fuel efficient vehicles. The V8 engine did not fit that narrative so it got the boot. Also, GM Holden were also looking at canning the 5.0 litre V8, however, a campaign from an Aus motoring magazine "V8 'til '98', assisted in Holden in retaining the V8 engine. Obviously Ford realised that they got it wrong and re-introduced the V8 in 302W EECIV version in 1992. But by then, the Clevo was long dead and never to return. I have never seen nor heard of Ford running testing programs on EFI 351C. I believe that it was their intent to get rid V8 powered passenger cars ASAP. The V8 F Series is a different story though. This can be related back to the North America market re the A Code engine namely 460 4V. In 1978, the CAFE rules showed that the 460 was impacting Ford so it got the boot - passenger cars, from 1979 on wards - say hello to the 400 2V. However, the 460, albeit in EFI form, went through to 1996 but only in commercial vehicles.

Mane journals on the Cleveland are smaller the 400 was produced then ford put a 351 Windsor crankshaft in the 400 that destroked it and came up with 351 cubic inches thus modified the 400 351m

@@mikereeves8689 Ford did not put a Windsor crank in the 400. The 351M is a completely different crank.

@@jesse75… you’re absolutely correct about the crankshaft comment. There’s definitely no shortage of misinformation pertaining to Windsors and Clevelands 🤷‍♂️.

I am an aircraft designer, and I had a FMX in my 71 Torino. I wanted to put a ratchet shifter in my turd, They don't make an interface for that trans. I measured the shift point lengths, and did a bunch of math during boring meetings at work. I finally came up a way to make a B&M shifter work. I designed new mounting plates, and adjustable cable linkage on my computer. With some help from the guys on the floor I had the plates water jeted and bent up. After too much time I had it all installed. The only FMX slushbox with a ratchet shifter in the world. It was still a turd but it was much cooler. I can't remember how I did it but I have all the dimensions written down in one of my old meeting note journals. Something to do during endless meetings.

@@mikeglick3507 I had a similar problem getting a stock column shifter to work correctly on a 66 Thunderbird that someone had cobbled a 1968 C6 transmission into. Ford had just introduced the C6 that year and later production 1966 Fords used C6s although the majority of 1966 Fords used Cruise O Matics as C6 production did not ramp up very fast., The Cruiso was the same as an FMX except that the FMX had no rear pump and a different shift quadrant and the shift control lever does not interchange with the C6. The C6 used in the 1966 Thunderbird had a unique transmission lever, while all other C6 applications had different geometry in relation to the arc the transmission lever travels through than on the later C6 units.. I found a late production 1966Thunderbird with original C6 in a wrecking yard and took all the linkage as well as the 1966 only C6 valve body (green dot drive rather than select shift) Not wanting to give up the rare linkage, I duplicated its function and dimensions by modifying the existing rods and transmission lever using a piece of steel and a drill. With trial and error (no math-Im allergic to it) it all lined up properly eventually. The FMX later evolved into the AOD, AODE, 4R70W and other variants, all descendants of the original 1951 Fordomatic.

Ford never produced a 4 barrel 351M/400, however Edelbrock makes a 4 barrel intake for those engines, it sells for about $420 new. Chilton manuals list a 4 barrel 400 for 1971, but Ive never seen one, and the rumor was that it was cancelled at the last minute due to emission issues. 385 series engines (429 and 460) can also be dropped in as they have the same trans configuration as 351M/400 but requires discontinued big block engine mounts from a 72-76 Thunderbird, 72-76 Gran Torino/Elite/Ranchero or Lincoln Mark IV if installed in a mid size chassis.

This. The Winsor has a better bottom end and a better oiling system. The 351C is a MONSTER but only if you have one of the high compression motors with the good closed chamber heads, which are pretty rare. There are aftermarket heads for the 351W that flow just as good, or you can put the good Cleveland heads on a Windsor block and have yourself a Cleavor that rips.

Yep I worked at a Ford dealership back in the 70s and 80s. I've owned and worked on just about every ford engine made . I have to say tho that I never cared for the FE series of engines. Just my opinion.

@@danielgreen7159 Nice!!! My first trucks had FE engines, got a '75 F-100 with a 360 in it and swapped it out for a moderately built 390. I blew a couple of them up, but definitely more my own fault than the engine's fault. I'd love a '70's Ford truck with an FE 390 in it again... Not so much because they're good or bad engines, but for that nostalgia. '76-'77 if an F-150, that front end looked the best! Or a '78 Bronco.

Late 70s ford trucks , absolutely the best looking trucks ever. I had a 79 with the 400 engine. Ran great but sure liked its fuel.

20 degree heads will NEVER flow as well as canted valve heads with all else being equal. Edelbrock makes a set Cleavor heads & intake to make a 351W really run! @@northshepherd8010

The 351M/400 is NOT based off the 385 Series it is just the 351C with a high deck and larger diam crank. The 351M/400 is what the 351W is to the other small blocks. It is NOT based off the 385 Series.

Truth

All this hype! A 351w will use the same engine mounts and bellhousing as the 5 liter! The deck is raised up from the 8.2" 5 liter height to 9.5, although the first few had 9.48" deck. I've ran both. The 9.2" Cleveland, the 9.5 Windsor, had the smallblock bell housing paytern. The351m, which is eccentually a 400m with a 3.5" stroke,The m series had the same belhousing pattern as the 429- 460 engines. They were in everything from thunderbird (I had one) to 3/4 ton trucks, which is the only logical application since the were hard on fuel but had good low end torque. The Windsor was a much better choice for car applications. It's ability to bolt up to the same bellhousing as the 302 makes if an instant upgrade, however it is obvious wider, and taller.

@@markmccarty9793 The 400 block so the 351M block also used the small block 6 bolt bell housing pattern. The big difference is the 400 blocks used the 385 series motor mounts where as the 351C shared mounts with the small blocks.

@matthewq4b no, there was on exception. I'm 63. Been doing this for decades, when ur mom was still powering your raw ass! The 77 thunderbird had a hybrid bellhousing- transmission combo that was just a bastard child! I had one. Got rid of that15 mpg mofo! These were decent truck engines, but you might as well had a 460! More torque, just a hundred pounds extra! These old M motors are boat anchors! Just put a 460 onto it and be done with it! I've heard of old M's having dual belhousing patterns! If you need more than the 351w just jump to a 460! Been there, done that! Spread that "M"anure round your wife's flowers! Have a great day!@

Bolt on yes- run correctly? Fat chance unless you know your stuff.

@@P_RO_ really , hmmm , easy , Amazon sells intakes to fit a clevo head on a Windsor now $157 and clevo heads on a Windsor 351 will run better , better overall engine , longer rods more deck height , in fact Dan Gurney destroked a 302 Windsor to 150 ci with a super short stroke and ran 4V Clevo heads with 2 X 1250 dominators in Indy around 1968 it ran 13000 rpm , should read his book !

The 221s were easy to identify, as they had no "harmonic balancer" on the front of the crank ... just an external counterweight and mount for a lower pully.

I think Kaase engines used a 400 based engine on the Engine Masters challenge a few years ago

Good info. In late 77 when the F-series was reworked. Was that when Ford made the switch from the 360/390 to the 351/400's? I had a '78 Bronco with a 400 and a '79 F-150 with a 351M. The 400 was ok. That 351, not so much. Although it was lifted and turning some huge, noisy mudders. Can't recall what they were called. Man they howled

Mud Hawgs!

The BOSS 302 head was not just a 4bbl Cleveland head. The C6 was behind a variety of engines and as such there is no C6 bolt pattern as it came in different flavors with different bolt patterns.

Did you not understand what he said ? The 351C is basically a small Big Block. It is closer to a Big Block than it is a small block. Your point doesn`t change this fact.

@@rodneyjones4890 he literally said the 351c has a big block bellhousing pattern, which is false.

@@rodneyjones4890 6:30 thank you have a nice day

@@mikecam94 SO HE FUCKED UP, GET OVER IT YA WANNABE EXPERT.

@@rodneyjones4890 No the Small Blocks 221-351W are the small block big blocks. They both share the same design linage. The 335 Series 351,351M ,400 are their own deal, the 351M/400 dimensionally are not far off the 385 Series big blocks. The Small blocks and the 335 series share the same bore spacing and head bolt pattern, the head bolt pattern is the same for the 385 series but is dimensionally different as is the bore spacing..

Modified.

Like I said in the video Ford never specifically said what the M stood for. Most agree on Modified but Michigan and Midland were also brought up.

I've heard it called all those names ive always called a modified I have one can make them run with right set of heads

@@cjponyparts Internally in power train engineering at Dearborn and Oakville it was designated Michigan to follow the naming convention of the other 2 351's being named after their original casting plant's, later the 351M was also cast at Cleveland. Modified was used later on as no one wanted to officially name the engine after the troubled and bad luck Michigan casting plant so it just called the 351M. Techs adopted the Modified moniker as the 351M is a modified 400. And it was jokingly said it was a 400 modified in to garbage. No one really knows where Midland came from but it's not correct and has no foundation for it's use.

Ford had some machining tolerance problems around that time. My grandpa bought a new 78 Ford 3/4 ton 4x4 with a 351M for the farm & it destroyed a couple C6 transmissions. They finally sent the dealer a jig & found that the bellhousing index pin holes were machined off several thousandths of an inch causing side load on the converter bushing & pump. Offset pins were made & the problem went away!

Y block ? I don't think so. Never heard a Cleveland called a Y block. Y blocks were done in like 1960 ish

@@oneninerniner3427 had a 71 mustang and it was a y block, Ford had a lot of leftovers in many production vehicles, not hard to tell, half of the timing cover was cast from the block out, many others have aluminum plates for the water pump, 71 is still 60 ish, so if you want to argue? You'll do it alone

The boss 302 only had canted valves because the heads came off a clevleand

Boss heads were similar to but they were NOT Cleveland heads. The Cleveland heads evolved from the Boss head's design & both 2V & 4V C heads had smaller ports & valves than the Boss heads. The Boss heads came out a year before the Cleveland engines. The Boss 302 was first offered in the 69 Mustangs, available in late 68. Clevelands didn't come out until the 70 model year, or late 69. 71 or 72 was the first & maybe last year for the Boss 351. The "performance" version of the 351C was called a 351HO & advertised HP was 300 but it was quite a bit higher HP than 300. The "big" heads for a 302 Windsor were 351 4V Windsor heads installed on a 302 block & required changing pistons to keep the comp up & special head gaskets to prevent a water leak between the block & the heads. @@72xafalcon

Unless somebody replaced the Clevo with a Winsor it would be a Windsor

Add a 400 crank and TMI pistons...

I remember that some of the old 'Hot Rod' magazine books had economy performance builds and upgrades for these engines. There's a lot of potential in them but Ford USA never tried to get it out.

Use a different engine.

Then something was wrong with the cleveland

Although I found a cast iron 351W 4V intake with a Ford Spreadbore 4V carb & put it on my 77 Ford van, I have never seen 1 in a vehicle or in 1 piece. My buddy had a 72 Torino GT with a 351C HO, a C6 trans with a factory stall converter, & the "police" handling package that was a BAD MOFO!! NO 351W would run with a Cleveland because the "canted valve" C heads were extremely superior to the 20* Windsor heads. This is the reason the circle track guys started building Cleavor engines before the days of high performance over the counter heads.

The M blocks & Modular blocks have almost no similarities,

@@bradgriffith4231 Kinda figured as much. Thanks for the reply and clearing that up.
