Engine Help 300c.i
Well i have a 77 F-100 Custom with a 3spd manual tranny 2wd with the 300c.i in it, I havent driven it yet because it needs a new, clutch and flywheel. Anyway what can i do to the motor to give it more power? I dont want it to have monsterous power but more than what it has stock. My budget is about $300 a week, so i can get new part every week for it. But can someone tell me if the engine is even a good one to be in a truck this size?

Once you drive it you may find yourself in shock at the torque this engine has and may be happy with it as is. Yes this is a great engine to have. It will push this truck around with no problem.
Congrats on your truck.
And welcome to fte

The 300 was originally a stationary engine, then it was modified for truck use and used all the way to f700, its a real truck engine. It doesnt turn high rpms at all so dont push it. and it may go slow but it will always go, no matter how much weight you have behind it.
And these engines were built to last. They will easily go over 300K if taken care of.
I dont know much about power mods for these engines, iv never needed any more from them. But it might be nice to get even more torque.
I think youll learn to love it in a truck
Good luck

thanks guys for all the advice and opinions. I dont want it to have tons of horse power i just dont want it to be bone stock either. And thanks for letting me know that the motor in my truck will be a dependable one for my first truck.

Transmission
Congrats on your "new" truck.
Before you do anything to increase your motor, take a good look at that transmission - and rear end gear. My "old" truck is a 79 f150 300 3spd with 2.73 (or is it 2.72?) gears and 235/75 tires. No problem on the highway, but off the line grunt is a little lacking, headers and a 4bdl aren't going to change that. It's not lack of power, it's lack of gearing.
If your geared low and you plan on doing a lot of highway miles you may want to look into an overdirve transmission, flip side if you want to use it for general purpose work or as a farm truck and your geared high a T18 (or equiv) would be just the ticket. Of course a ZF 5 speed would cover both ends.
Making more power is fine on paper (or a message board). Making power in an rpm range you will use is much better. Beware of advice from people who want you to turn a 300 into something it's not.

thanks man, yes i def need to check the rear end and tranny. The clutch is blown but this truck used to be a automatic and i dont think anyone swapped out the rear end when they converted it. Ill be doing alot of highway travel and just want a good setup with a decent amount of power. I just cant afford anything over the top $ wise but what rear end and tranny would you suggest for a decent amount? Also this truck has no power steering or power brakes, its all done using muscle

I would say that the original tranny was a C6.You can convert it to power brakes and steering quite easily,as all the needed items are available at your local parts house or salvage yard.IF you convert to power brakes,be sure to get the porportioning valve from a salvage yard or from BOTP(R) or LMC(R) or as a last resort,from a Ford dealer(BIG BUCKS).Leo

Hi Fordman1090,the 300 was a TRUCK engine originally.It was used in many industrial applications though.Such as generator/welder setups,irrigation pumps,wood chippers and even marine applications,just to name a few.Leo

Some WERE used in tractors.BUT only as field mods by the owners,as far as I know.And incase you did`nt know,the 300 is basically just a stroked 240.The crank,rods and pistons bolt right into a 240.Instant 300.Leo

When i say tractors i mean machinery. Made dad used to have equipment that ran the 300. But now everything is diesel.
Ya i knew it was a stroked 240, and i'v seen posts about switching heads between the too to get more power. but i dont know if that works.
Thanks.
