632 BBC HOT ROD SERIES:  *$22,000+

*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. It will run on 91 octane, and is happy being street driven while giving some attitude. You'll rarely adjust the valves with hydraulic roller lifters. Each engine is broke-in and dyno tuned to perfection.
