hey guys ive got a 351w in my 77 ext cab im wanting to swap a Cleveland into it and i was wondering if the body mount part of the motor mount would be the same? thanks for the help

 

Yes sir it is

 

cool so i would just need different headers/manifolds correct? 351m headers would work wouldnt they?

 

The headers will bolt to the heads, with the assumption that it is a 2V. Dont know if they will clear the truck.

 

You say 351w in one post, 351m in another. What do you have in your truck? Your vintage is usually the 351m. Bell pattern is the same as the 385 series motors. (370/429/460) The 351w is SBF pattern.

As for a 351c, it is SBF pattern too, so that would work IF you have a W.

 

i think he was saying he wants to use headers designed for the 351M in this truck for the 351C in this truck. basically using something meant for the purpose he wants, just modified. no pun intended

 

You are probably correct. Since the 351c is a much shorter deck motor than the 351m, those headers might hang a bit low. And being narrower, some other issue might pop up. Or it could fit like a glove. Measure first.

 

ParkerParkerM is correct. sorry for the confusion. thanks for the input as well

 

If the engine mounts on the Cleveland are the same as the 302 and 351w (as the bell housing pattern is) then I don't think the frame engine towers will fit from a 351m.

With both engines out and rubber mounts on engines, measure from the rear face of the block (trans mating surface) to the center of the rubber mount stud. The small block stud is farther forward than the 351m. 7/16" I think.

 

They are the same perches. Ive done it in a 77 -400 to cleveland and 73 - 302 to aforementioned 400

 

A true 351C has the same engine mount bolt pattern as the 302/351W, and same small block bellhousing. Or put 351C heads on the 351W, best of both worlds!

 

Clevor, i havent seen one of them in awhile
