Quote: Thanks I have a buddy building a big block to try and run down my small block. I know he has a 400 block and was just at his engine builder and say his 4.15 crank and just wondered how big of size it could be.
should be to hard...lol Most guys run the 471-472ish kit. They seem to run real good. Buddy ran mid 9's in an all steel 3300lb+ duster before going to the 500inch low deck, he was in the 9.20's this year. Not bad for an old foot brake car.
