I've got a 95 mustang with shorty headers, cold air intake, cobra intake, 4.10 gear, aluminum driveshaft, 2 1/2 flowmasters w/ h pipe and it's a 5 speed. I am going to check out a used polished kenne bell that is for the stock lower intake. What should I look for when checking it out to see if it is alright. The guy said he ran it on a stock motor with a 3.27 gear. Any help would be greatly appreciated. Thanks.
