Thinking of going away from the LS stuff and getting a big block chevy together. Thinking around 540ci and would run twin 76s or 80s. Dont really have a power goal, just want a high 7 second time slip. The car is mainly going to be a street car, so I would rather it light off on the street quick instead of waiting for a bunch of RPM to spool. Wondering what I should do rotating assembly wise. Figured id get the 9.8 M block, or go with a 10.2? Would like to do Holley EFI and run on pump gas for the street. Would I be good with like Callies Compstar rods and crank? And what head would be good for an application like this? And where is the go to place to get BBC parts/knowledge?
