Ok I know it would be totally a guess (or maybe not if someone can do the math) but I am wanting to know how much gain I could get (hypothetically of course) by switching rear ends. I am currently running about 300hp through a turbo 350 tranny with a 2.73 rear. the truck weighs approx. 3000 lbs. If I am getting low nines in the eighth now, what, hypothetically again, could I expect to get with a 4.10??. Assuming perfect lauch and no tire slippage. Would anybody be willing to take a guess? Would High sevens be hoping for too much.

Any thoughts will be appreciated
