I just lost 2 paragraphs...Looking for help on advice for making 3780# go 10.35 again, or faster. I have the engine on the stand. currently a 252/258/ .630/.630 with 1.5 ratio. Solid roller ported 915's. this engine was taken in trade from a guy that ran it in "pinks". We have no baseline with this engine. Thanks for helping out. Been building engines for 40 years, just not many rb engines..
