I have a Factory Five with 302 EFI with The Trick Flow Twisted Wedge top end kit. Aprox. 360 HP at the flywheel. 290 at the rear wheels.
Thinking about changing rear end gear ratio. Currently 3.27, no trac lok, 7.5 rearend (at least that's whats stamped on the outside of the unit)
Thinking about changing ratio to 3.73 with trac lok.

My question is will I end up with a noticeable and dramatic difference in acceleration. Enough to justify investment?

Thanks for your input
