Cast Iron SBC Pro lightweight Engine Block
World's new Motown Pro Lightweight block offers tremendous performance potential in a new lightweight package that will appeal to both circle track racers and drag racers.
Weighing in at a nominal 178 lbs, the Motown Pro Lightweight is cast from a special 40,000 psi iron alloy for increased strength while weighing significantly less than typical aftermarket blocks. The new block is available with either a standard SBC cam journal and lifters or with a BBC cam journal and .904" lifter bores to provide enhanced valve train stability and performance.
Ductile iron main caps are fitted with 4 bolt splayed caps on #2, 3 & 4 and 2 bolt caps for #1 & 5 which allow easy oil pan fitment. The main caps are secured by high strength 7/16" ARP bolts for maximum stability.
