351c crank vrs 351w

[igotaneed4speed]

A 351 w crank is basicly the same dimensional as a 351c other than main journal size and counter weights?


Bascily i have a rotating assembly for a 351c thats brand new all fordged stuff that i cant use and i have this 351w block.. can i have the mains turned down and it rebalanced to use in the 351w?

I'm guessing no. The 351w is a completely different block design than the
Cleveland "big block". The Windsor is basically just a stroked 302.

351w is larger then 351c so if its a crank for a 351c you would have to add material if it were possible

What about the bore spacing and rod thickness and such?

A cleveland IS NOT a big block.. in no way at all is it.

ok.. thanks i couldnt remember which one had the bigger mains..

im pretty sure a cleveland is the one with the bigger mains.

"google says"


351w 3.00"
351c 2.75"

Bearing spacers here we come..

It has been referred to by some as the "big block" 351 version to distinguish it from the Windsor blocks, although technically it's not.
Hence THE QUOTATION MARKS!!!:icon_mrgr

Do a bit of checking with hot rod magazine. They did a 351c crank in a 351w block a few years back.

Hmm. I've heard of the head swap, but not the crank. What is the benefit?

 

[igotaneed4speed]

weight would be one. .. alot of after market blocks all have Cleveland mains.. must be a reason..

Plus the smaller journal would be easier to keep oiled for higher rpm operation..
