Subject: Re: 4 Bolt Main Corvette Block versus Splayed Caps 2bolt LTx by JAKEJR on 2010/10/24 20:36:49 Using my new engine specs, with Engine Analyzer Pro V.3.9 simulator, the XFI 218/224 cam showed the broadest, highest torque band when compared to the 224/230. The 224/230 isn't listed in my catalog as a XFI grind but one of the mags had one custom ground for use in an engine build up they were doing. In Comp's catalog, the XFI grinds jump from 218/224 to 230/236 with NO 224/230 shown. I had to choose the 224/230 specs from the XE grinds, not the XFI. So that "could" make the difference. 224/230 would be the logical cam between the 218/224 and the 230/236 since many of Comp's cams move in 6 degree increments. I just ordered Comp's Camshaft Master Catalog, so maybe the XFI 224/230 lobes will be in it. If they are I'll re-run the simulation and post the results. But for now and for the engine I'm building for my son's 96 LT1 Vette, the 218/224 makes the most and best power. Could be this is an example of bigger not being better, but I'll know for sure once I plug in the XFI 224/230 specs (assuming I can find them). BTW, his car is a DD and the engine's being built for best torque NOT HP. Jake |
