Thanks for all the responses. I tried the online computer dyno to try to get an idea on how much torque vs horsepower the cams would give (ball park). All are in a good range,all will give, according to the program, 370 to 397 hp and 440 to 480 lbs torque, but the bigger 280 cam gives about 29 hp over the smaller 262 cam, and the smaller cam gives about 40 lbs of torque over the biggest. The Hughes cam and Voodoo cam are in between.

What is better for a cruiser? gain 40 lbs torque or 27 hp? Maybe a better question is about how much torque does a 383 need to put out to push the Road Runner with ease?

Thanks
Carl
