Thanks for the replies. Engine number 1. has been tested and made 575 HP @ 6500 RPM, very impressive when you consider the factory cam specs, I could see the vacuum coming in at 16 inches at idle. I ran the the engine to 6600 and was down 1 HP, I really like the way the 427 carries the power out, this is very important to me. Engine number 2. will be tested this week, I will post the results. Its interesting todays 236 headed flattop piston Super Stock 454 makes right at 720 HP, with the 049 headed version making 740. Ken, I would be interested in where your S/S 454 peaked?
