Its all good.You arent rambling,you are giving me good info for my build.I accept all info that you are willing to share.Thanks.No more power but I'm on the stock fuel system pumps and we had 12* of timing and we were at 11.80 A/F ratio and did not want to go any further. Outside temp was 36* so very good D/A. Jim Sr. has got so much experience with these engines and fuel management systems that when he said we could not make any more power because we were out of fuel I was really excited. 806HP @ 7600 RPM on 93 pump gas with 12* of timing was all I could ask for. Jim did say if I was to install the third fuel pump and run 100+octane race fuel he could bump the timing up to around 20* and this would have resulted in a gain of about 100 RWHP. I can't hook up the 806 RWHP so why spend any more money or time and just leave it alone. I have not touched a wrench on this engine in six years. As Jay (Bimini) said there is no reason to wring these motors out. My shift light is set at 6200 and my slow 65 year old reflex's probably let it rev to 6700 when shifting. Get it in high gear and let this engine pull like a freight train through the traps. Sorry for rambling.
