NRE Naturally Aspirated 632 BBC HOT ROD SERIES:
*Photos may show optional equipment. 850 hp This turn-key solution is a super strong workhorse of an engine. If you want the classic nasty Hot Rod sound, then this engine delivers lightning throttle response with MASSIVE torque everywhere and over 850 horsepower to boot.

Each engine is broke-in and dyno tuned to perfection.
