I had a couple ram engines rebuilt, one was a 1960 300F 413 engine with 63 300J short ram intakes and 3505s carbs. Stock stroke, stock compression, stock small valve heads with a very light pocket cleanup and a mild cam (similar to stock, went with a hyd roller) basically a stock rebuild but with lighter pistons and a warmer cam. I had it dyno'd and it performed well. TQ peak was at 3,600 rpm/351hp. Peak HP was 410 at 5,000, 421tq. It started falling off steadily past 5,000 rpm but the torque curve was very long and flat.
