So, those of you that have or have run roller motors... any comments on how you liked them? I've never had one before, but am considering getting one. It's a 454 with a Comp roller cam, roller rockers, 781 casting heads that are ported, domed pistons (was about 10.5:1 or so compression ratio), and Pete Jackson gear drive. It ran hard, but is currently apart to just re-ring and bearing and fix a valve guide that started wearing. The cam that was run in it was Comp Magnum hydraulic roller 260/260 adv duration, 206/206 @ 50, .510/.510 lift. I was thinking if I got the motor, about possibly going with the 280 cam with .566 lift... depending on how big of a cam I can go.
