OK, I have been following the 800hp n/a thread and was wondering what I could do to get a few more ponies. I have seen the 502 recipe from cyclone and widowmakers 502 pump gas build. My current engine is a BBC 505 with Merlin oval port heads, comp cams solid roller XR286 (0.653/ 0.660 lift), rpm airgap, holley HP 950. CR is in the mid 9’s. The plan was not to have a full on race high compression motor built that needed to be wrenched on before or after every trip, just a pump gas lake boat that would get going when needed. I just wanted to go a bit faster, but you know how that goes. I am running 81 now in a heavy 19’ Miller 6 seater, through Jacuzzi with the energizer with no real set up other than a custom loader, place’s short droop, and an FTN diverter nozzle. Per Duane’s chart I am at 478.66 hp spinning an AT A to 5100. After seeing these 502 builds at 740 hp, I think I am leaving some power on the table. I know set up is one of my next steps and have been thinking about doing a pump swap to a berk jg I have sitting around. I just think there is a bit more power to be had with my combo.
