I am putting together a 82' f-150 4X4. It originaly had a 351W. I can't decide if I should stay with the 351W or put in a 351C that I have. Both would have to be rebuilt. Does one out preform the other (HP/Tourqe/MPG/...)? Which is the better choice?

 

. The cleveland will have more bottom end grunt. but as for durability i would say go with the windsor.. they are bullit proof.

 

if you get the 351M/400 it has a c6 trans compared to the 351C with a c4 The 351 M is couppled with a 400 seires, has same stroke,cam,push rods as 400 family but in 351 block , more torque,so you need the c6 trans. the 351 C is just a 351. I agree with the windsor comment( bullet proof) But if your looking for power/torque go with the 351M/400. hope this helps you out

 

The 351C would have to have custom accessory brackets. Unless that you have the ones with the engine. Finding those would be tricky. THe 351C's were notorious for having thin cylinder walls also. Personally, I like the 351W with the 2v 351C heads on them, but finding a manifold would be difficult. I have a B&A Track Boss which has been out of production for some time now. Its all about preference. The 351w has been a great engine and will provide great service with plenty of power and torque. NASCAR engines use a windsor style block with canted valve Cleveland heads.

 

Windsor motors all the way. I built one a few years back for my short bed 1965 F100. It was an awesome motor. Mated to a tricked out C-6 tranny,it was a bulletproof set up. I'll tell you what I did to it,just for fun.
BOred .060
Forged pistons
13.5-1 compression
4" stroke
Comp cams custom roller- 294/306 duration. .612-.628 lift
AFR heads
Comp roller rockers-1.7 ratio
Edelbrock victor intake
Holley 4150 carb
Dyno-612 rear wheel horsepower

I turned this motor 8400 rpm. Never had any problems. They are truly bulletproof.

 

Heres a site that helped me out, hope it does the same.
