my dad used to have a '79 cj7 when i was little. the pervious owner swapped in a chevy 350, and it would roast all 4 tires. also my friends dads old room mate had a '70 something cj5 with a ford 390 i think it was. being the young gear heads we were we thought it was bad ass for him to do wheel stands at 1/4 throttle.
