I wonder why everyone worries about wearing out there engine with gears? So it rev's up I hold 4K and don't think nothing about it. My street cars run 4.10s and 4.56's the 4.10s run with short tires and the car still pulls like crazy to redline. Too tall a gear and the stall speed on a conv will be a problem and frankly in westren Pa with the hills I like to know that I can go up them just as fast as on the level. Most of the so called cruiser's of today are just plain slow due to carbon build up put a decent exhaust with something besides flow masters and the noise will not be the issue. Just my 10cents
