thanks again for the responses but I the questions I asked was not "please critique my cam choice". The cam has been a constant and I am aware that it,s not optimum for the new combination but my question is based on the changes that I made with no improvement in ET.

Changing the heads, increasing the rocker ratio to 1.6 from 1.5, adding a pro stock hood scoop that is sealed to the carb rather than the old school six pac scoop, lowering the stall by 500 rpm. Last time I did that the car picked up 4 tenths! Putting on a shorter tube header which was worth 20 hp on the dyno. Lastly adding a vacuum pump.

I thought that this stuff would make a a bit of a difference. But maybe not.
