I've never seen a naturally aspirated motor make more than 1.4 lb-ft per cube.....most well designed/built make 1.2-1.3
Mine is above that number. 525" B1MC making 775ft/lbs(775.8 to be exact)at 6300 RPM. that was on the previous fuel, new fuel has picked up a solid 2mph over the old stuff. That would put me 1.48, rounding up. FWIW my heads flow 457.2 cfm at .900". Cam is on the conservative side 280/296 851"/820 with a 113 LSA. The compression ratio also still is leaving some on the table at 15-1, it is not an all out effort as there is room to grow still. Good info here for sure. Interesting to see some of the results as well.
