Chevy 421 SBC
This motor was professionally built by R&R Speed and Machine in Huntsville, AL. It is brand new, NOT freshened up but BRAND NEW. The ONLY time on this engine is dyno and run-in time. It has never propelled a vehicle. This is a beautiful engine using only high dollar parts and the best engine builders! I have over $13,000.00 invested in this motor. It was built with nitrous in mind, (although nitrous has NEVER been ran through it yet) the cam is a custom nitrous friendly grind. I was planning to run a 300 shot to be conservative. This dynod at 705hp and 685 tq on engine alone. Swap out the cam if your not planning on running nitrous and pick up some more HP! Just had a baby so the engine must go... Will deliver free within 100 miles of Atlanta, GA. I will ship it to the lower 48 states at purchasers expense. This includes the engine only from the intake to the oil pan. Includes Harmonic Balancer and flexplate. Does not include starter, alternator, carb or distributor.
GM 2 bolt block professionally race prepped - $2327 was spent just in labor getting this block race ready. It has been hot tanked, magnafluxed, pressure checked, surface decked, bored .030 over, new bearings, freeze plugs etc.
