i wanna build up a nice lil sbc for my 84 cutlass.. i heard the 400 sbc is a nice little motor. i figured i get a 400 bore it .30 over.. put a nice rotating assembly in it.. my question is what cam should i use? i want it to run on pump gas because it gonna be a street/strip car.. so no crazy compression ratios. has anybody ever built a 400 sbc? does anybody have any specs or build ups for a 406 sbc build? any ideas/suggestions would be appreciated
