Not getting any response from the gmc forums so I'll try here instead,I am curious to know if this would make a difference ,I got a 82 gmc pickup with a 350 with 10.5 to 1 pistons,194 closed port heads,264 - 214 camshaft and am wondering if it would make much difference to put a 400 crank into it?

anybody???

yes you would be building a 383 stroker but you must machine the crank and you'll need the rods as well

Thats what I thought but I just wanted to double check and see if I was right or not.

I am probably mistaken, but I thought that putting a 400 crank in a 350 would give you 377. Then boring 30 over would give you 383. Maybe I'm backwards. Can you put a 350 crank in a 400 and get 377? Why in the world would anyone want to do that, I don't know. But would it?

a 400 Crank in a 350 block gives you a 383

a 350 Crank in a 400 block gives you a 377.

Why would you want to do that?

Well as we may or may not know, a 327 is a high reving engine.

a 377 is basically a 327 but with more Cubes... i.e. more grunt. Same way the 400 is like a 350... just has more grunt to be had.

I could be wrong... then again What do I know... I drive a Nova.

Know what also sucks? I have a large stack of Car Mags... one of them... has an article on odd ball strokers. It would of been handy, I could of given you more info. But Murphy's Law would have it... I cant find the darned thing.
