408 Scat Stroker Kits

Yeah, most of the guys I race with that have 4" crank small blocks are at max HP by 6200-6800. No reason to spin it higher...that is the main benefit to the 4" crank, big power at a lower RPM. My current motor pulls hard to my self imposed red line of 7000 (I have a rev limiter at 7), but there is probably no reason to go over 6500...my old 410 stroker ran the same ET shifting between 6000 and 6500.
