Here is my bench racing question; What engine makes more average power? Before looking at results, choose what you'll go with; (a) 500ci with 600 ft/lbs @ 3,500-5,000 (b) 400ci with 500 ft/lbs @ 4,500-6,000 (c) 300ci with 400 ft/lbs @ 5,500-7,000 - - - - - - - - performance being the only...

Okay fella's, I've chosen that I'm going with the 3.915" stroke/6.535" rod (470ci) rather than 4.250" stroke/6.535 (512ci) for my build. A bit more compression height, dramatically less piston speed @ 6,000 + RPM, rod-ratio is much better. Compression ratio was chosen for the ability to run...

Just bought my last set a week ago, and they are already arcing on the fender and have two jumping spark; Ridiculous that I am dropping a cylinder after only one week of use. What is the absolute...

Basing the fact that I am running a 451 with 10:1 CR, .590MP camshaft, Victor 440 intake manifold, and Edelbrock Performer RPM heads. I currently am running a 750 holley :laughing1: with a proform billet main body, metering blocks, and base plate. Would I gain enough power to warrant the change...

Just installed the .590 Mopar Solid Flat Tappet Cam... Sounds wicked! Set valve lash, .030/.028 per instructions from Mopar for aluminum heads. Two to three threads showing on Crane Ductile Iron Adj. Rocker Arms when adjusted; guessed on push rod length, so pleasantly surprised. Here is my...
