Yup..gears and converter will fix the lo end but now you're heading to more of a race build and the all around
driver is sacrificed to some degree. I ran a warm 340 with a .230 duration cam and it was lazy. A 9 1/2" Dynamic converter solved the lo rpm power but the novelty wore off driving "through it"or "out of it" on steep hills or corners at highway speeds.
Here's a nice all around driver...I didn't load this video correctly so just restart the video and watch the first couple of minutes. Pretty much stock and would be a blast to drive everywhere with decent mileage. And i bet it'll probably be about 14.5 give or take.
No..it's not a quarter miler
