I have a Holley 750 dp with the Proform main body with 82/92 jets and a 6.5 pv. I was just wondering if there was a performance gain/advantage to square jetting and plugging the pv or just leaving it alone. This is on a 410 SB stroker that is mostly used for racing, limited street driving (and yes, I know this combo wants a bigger carb, but that will have to wait till next year).


67 Barracuda street car, 408, e85, 1.38 60', 6.44 @105.9 in the 1/8 mile, 10.19 @130.5 in the 1/4...so far....
