Well, I took my 63 to the track yesterday, and was not pleased. I knew I needed to do some tuning, but now I am rethinking my combo. I have a .030 over 350 with trw flat tops, a 292 / 501 comp cam, cast 1.94 heads, roller tip rockers, victor jr intake, mallory unilite mechanical advance, 850mech secondary carb, 350trans with 2800 convertor, and 12 bolt stock rear with a 3.7 is gear ( have not checked for sure). Best run was a 10.4 at 70 mph in the eigth. I know the carb is too big for my combo, but I had it and its brand new, I am thinking now going to a 280 grind cam, performer rpm and summit aluminum heads. Am I throwing in the towel too early. This thing sounds great, revs quickly, but doesn't start rolling real good until second gear. Any advice would be appreciated.
