Awesome! Thanks

The Horsepower Monster did jj. N my mom I 2.\

Class is in session nice break down whats what .

@@TheHorsepowerMonster ppp

@@TheHorsepowerMonster pppppp

Thanks!

that head alone EASILY has $2000+ worth of porting,its also a $2000 head.weird /uncommon/unloved engines are great,they just cost a fortune to make similar power to an LS,just be fully aware of this. you can go get a junkyard 5.3 LS right now for couch change,throw in a $150-$200 cam and make 100 more horsepower effortlessly

I agree 100% and it's cool tech and ideas he has used , only downside is nobody makes aftermarket parts for these engines.. So an LS would be cheaper... and you could get some serious power with a 6.0 or 5.3 aluminum block that would be similar in weight, and even a mild build LS all told would be cheaper than just some of the parts he is using here.

@@trillrifaxegrindor4411 yeah but then you have to go about swapping it into the Jeep, which costs thousands

@@ivanfromtheeast4709 less expensive than building a custom engine! The head alone is gotta be upwards of $4000+!

Thanks! And thanks for watching!

@@TheHorsepowerMonster thank you, for making such a great content

Or you may just think you understand?! Nah, just kidding. He does do a fantastic job explaining. Everything I know about cars comes from gentlemen like this who share their knowledge firsthand. 👍👍

That's cool. I'd love to see one in person.

@@TheHorsepowerMonster I would LOVE to see a story about those heads

@@TheHorsepowerMonster I suspect the Jeep motor that German Turchetti was referring to was the "other" US built OHC six from the 1960s. That would be the Kaiser built Tornado. The engine was also built in Argentina by Kaiser subsidiary and used in AMC body styles that were no longer produced in the US. The motor is a completely different design commons.wikimedia.org/wiki/File:Kaiser_Tornado_engine.jpg But the again I could be wrong. If so there's probably some Jeep and AMC owners that would snap one up

@@germanturchetti6351 Could you send a link for the supplier

Thanks! And thanks for watching

The Chrysler 265 hemi can make 550 hp with carburettors so i reckon maybe that jeep engine may still have more ponies to unlock

With around 15 psi boost this engine should easily make 600 brony ponies!

@@kevintucker3354 Too easy there's no fun in that

I mean what a beautiful block , a GTR is basically I6, with forged crank and the right compression with better rods and stuff I bet these things could be real monsters... The wall thickness in the blocks is pure beef.

In Argentina this engines are making 350-400hp N/A from a long time ago, with only 188ci (race league limitations)...now with custom made 24v cilinder heads, they are just awesome!

That 400hp out of that Jeep6 is not even 100Hp/Litre. Still far from rest of the world For example Opel made 320Hp from 2,4litre inline in 1982....

Honda inline4, made from bottom part of K24 engine and head from K20 engine + stroker = 500hp out of 2.7L in N/A. Not joking. But still i love those older American V8s and sixes. And i love those videos. Cant wait for an episode with big V6! Might be GM 3.8L

The most impressive part of this engine is that it achives this 400hp at a quite low revs, 6100-6200. It does mean that the head flows very good, its not so easy with only 2 valves/cyl.

Jarek Nowak: the one who build 500Hp 2,7L should be working in Formula 1 racing. He must know something that worlds best professionals dont know. 🤣🤣🤣🤣🤣🤣🤣🤣🤣

yeah thats best part! look 1320 videos when they come to Brasil and they look our GM 250 l6 turbo with insane power. well this engines are heavy modified but run great constant 7sec on 1/4 with cast iron head hahahahah . Best Regards from Brasil!

Start looking into the L47 V8 that went into the Oldsmobile Aurora. It was used in LeMans Prototype racecars for 3 years, and Carol Shelby even took an interest in it for a concept car that unfortunately never made it to production.

What’s it in? What did you get

@@foch3 A 321 hp 331 lb ft Jeep Stroker.

I see this is from 3yrs ago, you still running the stroker? Been holding reliability?

@@XiiPuNiSh3RiiX negative. Gave the motor to my father. I have a TDI now. kzfaq.info/get/bejne/gdeXZ8R6v9vOqaM.html

Thanks!

You should have more torque than horsepower.

Power Block/Nation, is working on one currently. Look and see if there is anything new about it.

The Australian's have already done this, that is what a Barra is with its crossflow head etc. They can be built to over 1500hp on the factory iron block.

Jeff Pittman you should see the V12 a guy made with two 4.9’s

Vontay I love your Ford Barra engines! They rip. They are on par with the jdm RB engines!

@@deborahchesser7375 where's the link?

Ram 08 and above would be nice also with the 4.7 V-8 !

I miss tuning carburetors and setting points. Cars were so easy to fix 40 years ago

@@kevintucker3354 Me too brother.. especially the old fords you could do a tune up with a dime and a match book cover.. ;-)

Thanks a lot!

Thanks!

@@Future-Preps35 Tuned ITBs on this engine should be awesome too!! find the right lenght for the cam rpm range and you will get a strong jump in hp/torque band.. now match that rpm range with gearing in the Jeep and that would be a super fun vehicle to drive

Yep, makes the same power as a junkyard $500 LS with a cam and valve springs.

Ehh one is cammed mildly to be a street car, the other is a $$$$ race motor that is still crippled by a reverse flow head

Your kidding right ?? Get Real dude !!!

@@calebnation7797 What race motor, this 4,2 makes max power at 6200rpm, thats only 400rpms higher than max power in stock LT5 with 5,7 4-valve (and same 400hp). It is perfectly streetable.

Can the 4.0 swap into a Dakota without extensive cab mods?

Exactly! Please produce all the parts required, PLEASE!!!

head and head work ALONE is in the $5000 range....this isnt a budget build,its a $15,000+ engine

Its on a stand..i bet its no more then 300hp on the dyno.it weights a ton and do you see how slow it revs...definatly slow..made to pull or climb.

@@upnorthviking823 yes I know it's on a stand and that doesn't translate to WHP and that it's made for torque based application. It probably cost more than most regular builds too. But I still think it's cool. I've seen 1000+ LS and Ford v8 builds. I just find these "other" builds fascinating.

Unfortunately there is no aftermarket for a slant six cylinder head, I think it has been out of production too long and a lot of the surviving cars were V8 swapped. The Chevy 250 is in the same boat, having gone out of production in 1985.. Similar for Ford 300.

Just look to Australia. They build crazy Ford six's all the time.

@Rusty Climber The Barra head will not fit on the 300. The Aussie Ford six was based on the small six. Be just as easy to just buy a Barra.

Would make a perfect swap for an xj

Yeah, with the work put into it, you'd think he'd build a proper wedge shaped plenum with trumpets inside for the turbo intake

@@lobmin once turbo'd the trumpets dont do much for air flow, but in this case I think he would have seen some mild gains

@@jaytrapp71 he will definitely see high rpm hp & torque improvement. You can see he is losing high rpm power while having better numbers on low & mid rpm. That's a clear sign of a distrupted airflow which normally seen on high rpm examples. Plus intake response would improve too.

Dave Micolichek I think you should check his web site...the cost to build a stroker my self vice what his cost make it seem a no brained to not build my own...I just wonder what the difference is for,the MAC daddy.

@Dave Micolichek no the price i saw was for the "garden viraity" stroker not the Mac daddy... there is nothing intended at all. i thought my reply was self explanatory with no offense intended

Let's design one and carve it out of billet or cast it and rake in the $

One word, money. One reason Edelbrock did not do a cross flow head is CARB. If one gets creative you could fabricate a new cross flow head out of a couple of Ford or Chevy small block heads. The bore spacing is exactly the same as the Ford and only .020 over the Chevy. The big issue is the ignition system. The intake needs to be on the intake side to keep the pushrods away from the exhaust.

@@mpetersen6 I've looked into this a bit and think that the Australian 351Clevland head would be great with the splayed valves. The bore spacing is correct as is the bolt spacing lengthwise but crosswise the Jeep engine is narrower and one of the end bolts is in an offset position. Some bare undrilled heads, some aluminum welding and some machine work should be all you need.

@@jamesford2942 Others have done thought exercises on this too. Somebody may have even tried it but either it didn't work or it was beyond d their skill level. If somebody could put LS heads on a Ford inline 6 you should be able to do this. The Ford 240/300 has a BC of 4.480. The 144/170/200/250 is 4.08. Too bad the Barra isn't based on the same BC as the Windsor or Cleveland. That would be the way to go. On one of the Jeep sites there was an image of a cad drawing that showed the head bolt position of the Ford and Chevy Small Blocks. I wonder if it would be practical to bore out the whole cylinder wall and install sleeves that are then welded or silver soldered in place. The 4.0 block has a pretty high nickel content iirc* so welding should be easier. Re-deck the block and straighten the main bearing bores out. Incidentally the cam bearing were installed prior to the finish bore of the main bearing bores. The mains and cam bearings were bore at the same time to maintain parallelism and center distance. *The nickel content may have been really high initially. The early blocks on some machining stations the chips would come off blue. Not something you normally see with cast iron.

@@mpetersen6 I have gone as far as buying head gaskets and laying them over each other to determine the difference. I have a 4.0 a 258 Jeep engine and many Ford small block heads. Maybe a set of unfinished Edelbrock Cleveland heads would be a starting place.

manitoublack and the team: Im a total devotee to the Dorton families approach to great ignition and fue delivery. It fazes and amazes me how guys split the dual synch system standard with any 1986 onwards Sequential F brand TFi and call it progress, though!. Anyway, I've seen a seprate crank sensor for advance, cam phaser sensor for sequential solution on a Holley HP turbo 200 SEFi Ford. As long as you have two square wave forms, your in Fing orbit Buzz Lightyear! Lookes like a Bernstien sensor like Ive used. Very easy to blow up if misswired, but boy it makes great squarewaves which will allways be picked up. The Holley HP system is particular in that it "demands" two great signals if deciding to go full sequential, and doesnt deal well with Fords Spout out or 36-1 or 62-2 combined signals. When split signals arrive, it then delivers most excellent base mapping. Any Mopar guys from Australia...your 265 cubic inch D series Hemi builds will love this stuff. Not many will know, but our stock race E49s were making 295 hp net at 5300 rpm on Kiwi Leo Lenards dyno back in 1972, a constant of 265 cubes x 5300 rpm / 295 hp net, or 4761. It say another 50 hp net would be found with the increased cylinder pressure on a 265 Hemi if you used this management system. On this Jeep, its cal is : 280 cid x 6200 rpm / 395 gross hp. It's a constant of 4400. Constants like that are hard to get on non cross flow heads, which behave just like restrictor plate engines. Keith and his son understand thosd engines more than anyone on earth. David Vizard did it in 1985 with one Weber 48 on a 1400 cc engine, a constant of 4449 on a siamese port, three bearing non cross flow engine. If I recall. In a similar way Richard Holdener got it down to 3918 on one of his 5.1 liter Holley Hi Ram destroked LS 6.0 engine builds, 310 cubes times 8000 rpm/ 633 hp gross although even NASCAR engines are down to 3650 now. Gotta say...great work

Would be interesting to see.

Here my out. I want to see if anyone could use a v12 ls head on a 6 to make a crossflow

@Ragingbull340 the bore space is like. 05ish off

Hey thanks! And thanks for watching!
