crankshaft number help
 

is a crankshaft number 8832442 a 400 crank

3932442 is a cast crank, 3.48" throw.

To the best of my knowledge no GM cranks start with an 8.

thanks alot billy the guy told me its a 400 crank i just wanted to make sure im now that i know its a 350 i have to locate another 400 crank

Not sure what you are looking to spend but you can get a crank with 350 mains and a 3.75" stroke from Ohio Crank for like $190. Never dealt with them but I read generally positive results.

im looking for a 400 crank for the 406 build

Ohio crank has one for 400 mains as well... $190.

thanks i will check them out
