After replacing the heads on my drag car, the engine wants to rev much higher and faster than before. Because of that, I changed the rearend ratio to a higher one only to slow the engine at the finish line. The question I have is that with the higher rear ratio, I have thought about replacing the stock first and second gear assemblies with an aftermarket lower gear kit to help the car accelerate like it did before with the lower gear set while still retaining the high gear ratio. Does anyone have any input other than computer simulations (i.e. real life) regarding the use of low gear kits? It looks good on paper but is it worth it? Thanks...
