well me brother had a 72 chevell with a 454, 30 over, with a custom ground circle track cam or some chit, the beefiest parts top to bottom, the parts alone cost 7,000, back in 89, never on a dyno but rated at 650 hp, had a B and M built trans, 3200 stall, semi manual valve body, 411 full posi rear. ran 12.6 in the 1/4 with slicks. over all cost of car, with the loudest stereo in town, it was a 12,000 dollar car.
it was his daily driver, and he loved every minute of it. the motor never gave him one problem over the years. just regular stuff, valves adjusted, tune ups fluid changes, and lots of tires lol
if you cant tell yet my brother got hit by a car while riding a moped, he got 100,000 grand, so it was the best money could buy at the time. and he spent it well. lol
