Im actually looking at a 351m engine now instead of the 302. Will the bellhousing from my 4speed match with the 351m? and the 302 mounts will work with a 351 right. Thanks.

What should i do and what would work with my 69 f100.

Both engines will have to be pulled.This guy says the 360 also runs, should i go with the 360, would it work with my 69?!?! need help quick, thanks.

the 351m bellhousing is different than the 360 and the 302 bellhousings. yo uwill need the correct bellhousing fo rthe engine you use. the 351m is a smog motor and needs work to be a good runner. the 360 is a truck engine just like everyone else has. the 360 can also be built into a 390 with a new crank rods and pistons. the 351m will still be a 351m when you get done modding it. just with more pep.

ok thanks, he says the 360 is currently connected to a 4spd std, the same tranny as I have. So if i bought the 360 it will hook up with my tranny and bellhousing right?

you will need the bellhousing that is hooked to the 360 now. the 302 bellhousing wont fit a 360 engine the bolt pattern is different.

I have an inline in right now. But if i get the bellhousing from the 360 and also ill need the motor mounts from the truck and ill be good?

yes that willl be what you need. i forgot about the mounts.

thanks for all the help fordman. You mentioned above that you can build it into a 390. Do you just need crank rods and pistons out of a 390 engine?

Bought the 70 f250 for $400 going to pick it up friday. kinda rusty but i want the engine and a few other parts

. By the way for the 360/390 conversion why would you kneed 390 heads if the 360 is the same bore as the 390? I heard all you kneed is the 390 crankshaft and 390 rods and your set for the conversion? Does that sound right? Thanks.

truck heads are all the same for 352 360 and 390. car heads might be different though. yo udont need to change heads to make it a 390.
