I have a pretty much stock 91 gt with just cold air intake, and mac cat-back exhaust. It has the automatic trans in it. My friends father works at a ford dealership as a mechanic and he said he will give me a set of 4.10 gears and will install them for 300 dollars. Before the exhaust, I was running 10 flat in the 1/8 mile. Will this help me and will i be able to feel a difference. Please help.

Thanks.
