I am surprised your only running a 4:56 and not a 4:88 . Even though it's a different combo, I have a 71 Lemans wagon I run in J/SA. To get it moving I have a 2.75 low gear and a 4:56 . Trap rpm is about 6500, I would think your 402 would turn at least that high. What rpm do you run through the lights ?
