I got a 4 door 81 malibu. I'm trying to put it together on the cheap for a footbrake bracket car. I'm probably gonna gut the interior, relocate the battery and drink some slimfast to save some weight. I got a tbi 350 (193 heads) with 420/442 rv cam 1.6 roller rockers and long tubes, 600 holley, performer rpm intake and a fresh th350 to go behind it. Im probably gonna put a mini spoil in the 7.5 cause I will only be driving the car 8 miles to the track and back home so its gonna see virtually no street time. I don't really count on the car having enough grunt to break anything anyways lol. From what I read I guess I can fit a 275 60 r15 on the rear. So my question is with the combo above what would be the best choice for a converter and gear for the 1/8? I know the car will run out of breath around 4500 probably and pull the hardest 2500-3000ish so I was thinking cheap jegs 2200/2400 stall and 373s..but I would much rather have someone's opinion....thanks
