    Talking rpm's here. What kind of rpm's can these 8ba motors turn without throwing rods out the side of it? Ive got a newly rebuilt flatty with max-1 cam, isky springs, stainless valves, 3 ring ross pistons and arp main bolts and rod nuts. Stock rods, and stock crank, fully balanced. What am I safe to rev er' to if i decide to take it to the strip someday? Sound amazing with the unbaffeled zoomies btw!:D Just let me know what ur guys' take is on this.
