marshall mcdowell the slant is a better motor overall. The 300 is still a great motor.

i agree the slant six is a great engine. i have heard of some still running with a broken piston

I've had several 300's LOVE EM. but I've also seen slant 6's that refuse to blow up LOL

Dude, I would respectfully have to disagree. My 96 F150 recently had a water pump go bad in it. That thing ran with absolutely zero coolant for 20 miles and absolutely nothing warped on it. Mind you, this is a motor that already has 195k miles on it and has never had a tune-up or any significant maintenance since it left the factory. There are precious few motors that will do that.

Mines got a bad water pump and runs day to day. But its the fact it pukes up coolant every so often from the water pump, combined with a shoddy fuel pump, and i end up vapor locking at low speed. But she gets me there everytime. No just going home is the problem.

it sounds like poo! You wanna hear a good inline 6 look up e38 hemi, first vid!

A 300 with manual is fun to drive.

He probably has a granny gear 4 speed.

@@MisterMikeTexas no, he has a 3 speed manual

In these motors, they have peak torque and horsepower at very low RPMs and don't wear well over time when you do this, as they were not made for it. I would recommend very highly against it.

@@Heartstrong_Productions Well, the 302 in my Mustang wasn't meant to hit 8800 rpm either, but it handles it nicely. lol It's a Ford, don't worry about it.

@@AmericanThunder saying that is a nice way to sound like a cocky know it all to people who have been down that road. Total apples to oranges comparison here. You're comparing an inline 6 that drives like a diesel and was specifically designed to run lower RPMs. It's a workhorse engine. A 302 is more of an all around motor. If you run that a little hot, you probably won't hurt it. Do it in a 300 straight 6 for any length of time, you will. I've seen it and it isn't pretty. You wanna see head gasket leaks, spun rods, warped heads? Go ahead, run one around 7,000 RPM for an extended period. I did, I don't recommend it.

AmericanThunder v8?

Thank you and good luck with your build!

And if you can find one, a Wayne 12 port head on your Jimmy

Thanks!

John Graves Where did you buy these parts? I've been looking everywhere on the computer and I can't find any performance parts. Is there a website or something? I need parts for my 1990 F150 EFI 300. The motor only has about 35,000 miles on it and the truck just hit 99,000 miles. Please help out, John; I appreciate it.

Well it all depends on what you want really. It will be a little harder for you because it is fuel injected but I got all my parts from summitracing.com. Its an awsome, safe website, you just enter the information of your truck or car into it and it shows most of the parts that are offered. Cams can also be bought on summit but if you go to the actual cam manufacturer website it is a bit more descriptive. Comp cams, Isky, Crane, and Crower are the major cam brands I can think of. Just take it slow read everything you can. Go to www.fordsix.com/forum.com, you can become a member and post questions or just lurk in the back for a few years like i did and read otherz post lol. They are all really friendly and helped me threw my build. Goodluck and be safe!

doublethreat07 how much power is your in-line 6 stang making

Nah, if you can find a 390, get that instead..waaay more HP potential. Avoid the 460's, thier heads crack a Lot.

Matt kinda does !!

I always thought my suped up 300 sounded like an old 70s inline six BMW racer. Either one is cool.

the cam lobes must be pretty flat

Had to put a muffler 2 way in 2 way out sounds a lot better now

Brandon Bowdoin my guess is a our speed with granny and he’s starting in second

The block and head were milled just enough to square then up. Not 100% sure but I would say somewhere in the 8.5:1 to 9:1 area.

Stock should be around 4000. At 5,000 it drops off

You don't know if a turbo will work with EFI? That's practically how every turbo system is. If you have speed density, convert to mass air and go to town.

With that statement I would suggest having someone else build it

I used the stock bracket but had to shorten it down. I also had to make a L shaped bracket that bolts to the stock location and goes back to by the 4 barrel carb.

Offenhouser makes them Summit racing and JEGS have them

With the Machine shop bill and parts it was anywhere from 1,500 to 2,000. I did all the labor on it when it comes to installing and taking/putting everything back together. I wanted to build the six because it's different. You don't see many people running around with a hot rod inline 6 cylinder as opposed to a V8. I'm sure building a V8 will be cheaper because there is more competition when it comes to the parts. Good Luck!, John

Most want the V-8 with the automatic. So many more parts available aftermarket, too.

If you add a Crower like the one I have in my 96 F-150, it added around 50 Horsepower. Which I thought was a huge improvement.

I had to dig to find the box this thing came in. If memory serves, I got this from Jegs. The exact labeling on the box is part "#19210, Ford 240-300 6-cyl. COMPU-PRO Hydraulic Cam 248 HDP. " Outside of that, I seem to have temporarily misplaced the file I have the receipts in for that particular build. If I find anything else when I locate said file, I'll post it. But this is what I've found from the box itself.

Doug Anderson damn I would've expected more

Eh. Probably a bit more. I get damn near 21 mpg in my 89 f150 5 speed 300 I.

My 79 only manages about 13. Granted I have 35s and 3.55s

Aaahhh. I took my 35s off and put standards back on. Helped with gas a lot.

Nicholas Merenda bout 3 gallons a mile

No where else I'd be!

John Graves hell yea!

That's not how that works...

gunshooter26 no they’re work engines mainly more torque than hp

+saglike93 It's a gas/petrol

It's obviously a diesel

+Eldridge Johnson it's obviously not because the owner said its a petrol.....

just picture a diesel that runs on octane. thats what this truck is.

How does a retarded idle sound stock

😆

Check out the updated video of the truck on my channel, you might like it more.

sounds like a cummins 6

Semi's are loud and slow too, but they also do work for thousands of hours and in the hundreds of thousands of miles. Much like the big daddy 6 will.

The damn thing redlines at like 3.4K, what did you expect?🤣

WebNstyne Please just go away, everyone else seems to think it sound great. Just because you don't like it doesn't mean we don't.

did I hurt your feelings with my unkind words? Get over it

6 into 1 makes it sound too refined. Definitely not what this truck needs. I think it sounds great.

i think she sounds good. most inline sixes have an inherent buzz sound to the exaust noise. unless its my efi 300 with a fouled cylinder then its putt putt

these engine were not built for speed more for torque with the cam he's probably making 200hp and almost 400+ft-Ib

Not true. Yes a 7 main bearing inline six like this produced gobs of torque, but with the right cam, carbs (plural) exhaust and ignition I have seen these put out over 400 hp. There was a nationally campaigned 300ci rock crawler in a bronco that was dyno'd at 600. I saw it. I have been building these 240/300 since the seventies. They are a real treat. Especially blowing off SBC's (actually quite easy). When they see what they were beat by it really pisses em off.

3RTracing cool to hear from someone who has been building them for a while. yea i have seen a video of one make over 500+ but never seen one in front of me. I want to build mine up to almost 600hp turbo charged and put it in a mud truck.

Please do. I watch this video a few times a month.

Still waiting.
