i swapped from2x holley 4781-C to 2x 1250cfm dominators 80532-1 with the same timing and OD,fuel.i went from a prior 10.35/131 1.35 60' to a 10.21/134 1.439 60' with a lot of tunning left as the fuel idle air bleeds are too rich and i dropped the jetting from a stock 100 to 95sq jetted.there is more to gain in the 60' adjusting tire psi and fuel.i should be in the 10.0 range after all done or better.i weighed the car finaly at norwalk 3640lbs + me 250 dressed to race.
