While you are figuring out all the frictional saving from the 2.200 journal from the 2.438 Ford journal, you also need to take into account that the Ford bearing is only .734 wide as compared to a Chev 2.200 bearing that measure .892 wide. Sounds to me like you not using all the pertinent info in your equation. By my figures it looks like there is 11% less drag with a Ford bearing for a 2.438 journal as compared to the Chev 2.200. Oh, my Crower rods are 6.488 in length and my pistons have the correct C/H number per NHRA.

With that said I think NHRA should take about 10 hp off the FE Crower rod Combo. How bout you???
