hey, i'm rebuilding the top end of a 400sbc i recently picked up for my truck. the motor was rebuilt but sat for an unknown amount of time and was in need of regasketing. upon tear down it was determined that the cam was wiped out, not to mention it was a crane 272 cam which is pretty damn big. the motor has a stock rebuilt bottom end with keith black stock 30 over pistons and good clean cylinder bores along with an edelbrock performer intake. the heads are stock style with comp roller tip rockers and manley valve guides. i figure compression to be 8.5-1 figuring a stock rebuild. i plan on regasketing, new cam lifters, timing chain, distributor, rebuilt q-jet, small tube headers, new bolts everywhere, new flywheel, and any other minor incidentals that may creep up along the way. i'm stumped as far as where to go with a cam choice. i'd prefer off the shelf grinds for ease and budget. i had in mind a few cams: lunati 60100lk or 60101lk or comp cams cl12-231-2 or 12-234-2. i know that with the extra cubic inches i can get away with a larger cam. this is going in my daily driven k5. the specs on the truck are: sm465 (6.55 low, 3.58 first gear), 2.73 rear gears, 32" tires, heat and ac. driveability are important considering its my main mode of transportation. any info is appreciated and if more info on my motor or set up is needed let me know, thanks -Josh.
