look at the 383 chevy vs 383 mopar dyno test, the chevy is 3.75" stroke and the mopar at 3.38" made equal horsepower and more low end torque. (both with- equal cams, equal compression ratio, intakes, headers, same carb. years ago car craft tested the 440 mopar, 454 chevy, 460 ford, 455 buick/olds/pontiac, equal-cams etc. and the 440 with the shortest stroke made the most torque and tied the bigger engines for hosepower. big strokers are overrated, go for the 372, I am happy with my +.020" X 3.48" 360 cu. in. 340 street car running 11's with J heads and pump gas
