Increasing engine displacement with a stroker kit is a proven way to get more horsepower and torque, but exactly how much power can you expect? In this test of “there’s no replacement for displacement,” the hosts of Engine Masters presented by AMSOIL and sponsored by Mr. Gasket and Earl’s Vapor Guard run a dyno comparo you’ve probably never seen before: two engines with all the same specs except for the crankshaft stroke. One small-block Mopar engine is a 410ci stroker, while the other is a 367ci stocker with an overbore. They use the same carb, intake, cam, heads, compression, and headers. You think the bigger engine makes far more horsepower? You may be in for a surprise
