will 3.73 gears kill my GTA ?
If im left with no choice but to use 373's in my 9 bolt rebuild as my 327's whine. This is a bone stock 87 350 im using as a daily driver and was wondering if 373's will kill this car...i dont push her to hard so im stumped on finding a used one or a rebuild with 373's.

you will loose your top end, which is limited because of the TPI design. Something like 3:42 or so would be the most you wouild want with a stock TPI setup.
