Thks Cliff, any idea where to start looking for the lost power, i tried adv cam with just putting it on the 4 deg keyway and put it on the same dyno and it was down to 240 rwhp so i put it back straight up, tried deg cam with a buddy but we kept getting some scewed up numbers so eventually we gave up, i need to do it again with someone who knows more about it. with the cam straight up it cranks 150 and when i put it on the 4 deg it cranked 165 on compression check.
built a pretty good bottom end with 5140 rods and KB forged pistons 14cc dish, 13 heads at 78cc ported using Jims book but did not go crazy, gasket match, ran the cutters down the bowl and blended, smoothed out runners and pushrod bulges,unshrouded valves.Built quadrajet using your book on stock 69 intake with tri y headers and 2 1/2 mandrel bent full exhaust.
Do you think deg cam properly will make a difference in finding some of the lost power im down 60-80 hp from what others are seeing.
