All I can say(knock on wood) is that I have thrashed for over 2 years a cup style, RDI rebuilt 358ci (660hp)motor. I adjust the solid roller lifters and thats it. I was banging the rev limiter at willow (8200 rpm) a few weeks ago on most laps. No car except for greg lapoint(sc347) has stayed with me on a straight. Wanta be racers like me don't usually break these motors. You can get plenty of power out of any motor to make a cobra fast. If you want to thrash it and have it last, there is no better way than a cup style motor. Scott
