let me elaborate some more on this^^^ . My first intent was to run a 13.99 with a stock 360 4bbl, stock exhaust manifolds, stock converter, and 2.45 gears. Everyone and their 2 yr old son knows those aren't go fast parts. But it was a personal challenge to myself. I've moved the goal just a little. But some do certain things for a class they are racing in. It's all about the intended purpose, not that all believe it's the "best choice" of all choices to go fast.
