im building a turbo fox body and i was wondering if i should run a 373 or a 355 gear. i want it to be more of a street car than a strip car. i was also wondering if i could trade a friend for gears he has a 06 mustang gt. would those gears be strong enough to work in my car or does it matter. also i was wondering on what ignition to run. preferably a good cheap ignition set up. thanks.
