World Products offers a new alternative for enthusiasts and engine builders on a budget, the MOTOWN II STREET block! The same, recently introduced next generation MOTOWN, but with a new lower price.

With a thick wall casting over many competitors, a big stroker build is possible, as the MOTOWN II STREET can be bored to 4.200” and accepts a 4.000” stroke. The water jacket features a huge 152 fl. oz. capacity per cylinder bank – almost a half gallon total more than the comparable GM Bowtie! A new oiling system design addresses any concerns about leaks as the distributor is now at the end of the oiling cycle. Don’t settle for anything less!
