[QUOTE="99svtvert, post: 4336868, member: 22962"] I have billet pump gears, billet timing gear; ARP rod bolts, and ATI 4.6 Superdamper (an expensive add-on). The 305 Modular that I am working on; has a solid roller valvetrain and double helix springs, stage 3 ported FR500 heads, and did have a FR500 intake (that has been moved to the 4.6) so it is intake-less right now. It easily turned 8250 early last spring. That is a unbelievable roar. As far as blown 4.6's, I don't think it makes any difference how the the RPM's go (6500-6800) after you stop making HP ????
