Honestly, I can't even remember some of the other stuff. The price includes the intake

Engine has been run for break-in only on the dyno, never raced. Using my junk Holley carb (off my dirt mini-stock) and stock manifolds the engine made 442 lb/ft torque. A/F ratios were very rich. There should be quite a bit more power available with some tuning and with a good carb and exhaust. I hate to sell, but the reality is that I've overspent on this project and need to let this engine go and find a used crate motor. The price listed includes the old Holley carb that I have and the ported GM marine intake. If you don't want the carb or intake, the price drops to $5500. May possibly take a used 602 crate motor as partial trade (at used value), may also take FWD 4-cyl car at part trade also (also at realistic value).
