ok, so the roller 5.0 is running smoothly...got a new 2.5" x-pipe exhaust with spintechs....yet i'm not "feeling" that this is what 86-93 5.0 should feel like. i had expected a bit more of a surge when i get on it, but can my stock gearing really be that slow? i remember driving this car at 16yrs old....couldn't even get it to barely leave a stripe with the orig 289 and holding the brakes... but with a new roller, E-303 cam, etc, etc, i can leave a little stripe on command, but i expected more. i imagine i may be leaving a bit out from tuning, but overall, is the gearing really affecting it that much? i also have a tci torq converter in the c4 and i can't go beyond 3.23s according to the box. would 3.00 or 3.23's make that much of a difference over the stock 2.79's? p.s. i plan on running 17" wheels if that makes any difference....thanks.
