My combo is
360 .30 over
Speed pro flat tops
Mp .484 cam
Eddie heads
Performer rpm intake
Eddie 650 avs

727 with 3000 stall

8 1/4 3:55

Car turned a 13.6 and was missing at the big end. I'm going to bump the timing down and switch to a Holley but the combo should be in the 12s and I don't feel it in it!

Welcome to the not running the times you expect should run club ! I can't break 13.3 and I know the car should run 12's . Dyno tested 398 hp 413 tq Mahle 10.5 forged Mahle pistons , light port on the stock heads , Air Gap 750 holley street avenger , 8 3/34 3:55 gears stock 340 converter and a Gear Vendors overdrive . 235 60 15 M/T drag radials .
What are your rpm when crossing the line ? I'm at 5300-550 rpm in 2nd overdrive crossing the line .
Going to follow this thread with interest .
