Quickest ever with my Valiant

What is great about this car, it is totally low budget. It has a bone stock short block, except for cam. Does have a $600 converter, and the "A" Body 4.56 SG 8 3/4 rear. The rear suspension is stock "A" Body 5 leaf springs, cheap stock shocks, and doesn't even have a pinion snubber. I am geared a little too deep, though. Going through the traps at over 6300 rpm. Maybe a 28-30 inch tire, or 4.11 gear with the 26 in tire. Next race is 1/8 mile, so I'm good for now.
