Mark, I didnt want to start a pissing match on drr asking this question so I will ask on here its a bit more civil
I wonder if you have ran the bigger cfm billet main bodies say like 1600cfm vs a holley 1250 main body. Reason I ask, what I see is a lot of power on the dyno and can never get them to be as fast on the track under accelration. Same goes for my injection (2100cfm terminator) we've been able to make awesome power on the dyno with my combo (25hp avg and 30trq avg better) but yet it does not run faster on the track.
David you are 100% correct..I have got a friend that does head work at Clements racing in Spartanburg S.C. where they CNC machine virgin aluminum heads for DART...and he states they face this issue all the time with heads etc...I am sure a-lot of this is due to the loss of Power thru the chassis set up etc....
Not to get off the subject But I have seen 30hp difference in 1/2 degree of pinion angle on chassis dyno.
side NOTE: I spoke woth John today at APD and they are gonna Convert my Stock 750 cfm Holley Carb to a e-85 CARB for the 73 z-28 camaro street car I have....$595 plus shipping !
