The old adage of “there’s no substitute for cubic inches” certainly holds true in the form of World Products’ MERLIN 632 big block Chevrolet. Increasing the displacement of an engine is a sure fire way to add horsepower and torque without placing undue strain on the rotating assembly or valve train. And it is for that reason that World Products can back an 800 horsepower engine with a 2 year/24K mile limited warranty (street applications only)!
