351w

Hi everyone. I know someone selling a 351w and transmission out of a 1986 f150 4x4. I figured the transmission won't work but will the 351w still bolt up to my c4 trans in my 1973 Mercury Comet. If so is the c4 strong enough? I plan on getting v8 c4 and rebuilding it.

 

Unless ur going "Crazy Power" C4 built right, can take lots of abuse/power.

 

c4 is a good trans,don`t need to put piles of money in one until you push more than 400tq & 400hp.

 

Can i use the c4 that came with my 250 six originally?

 

If it is a PEE version then it's built at least close to V8 specs...

You'll need a 351 C4 flexplate(same as pre '81 302) as the balance is different for the 250 and I doubt the C4 will bolt to flex currently on 351...

 

Thanks alot for the info everyone.

 

An '86 351 isn't going to make tons of power anyway unless you put aftermarket heads on it.

 

I used a c4 from a 1980 Granada that had a 250 in it. The 250 flex plate had 164 teeth, so I bought a 302 flex plate for a 1980 Granada (correct balance and 164 teeth). It is all put together, but I havent run it yet (still need to figure out cooling lines and column shift with headers). I have read that the clutch packs on the 250 c4 are the same as a v8. I hope I read that right.
