I bought some 3.73 gears to put in today and as im doing it i see the old gears already say 3.73 and i was so mad. My car already has em? It doesnt feel like it at all. I used to have a 89 5.0 and it burned thru first and second with 3.73 and my cobra barely chirps second gear. Anyone know whats up with my car. I ran 14.33 with 3.73 x pipe and pullies and timing at 15. Is that good? Anyone have any input at all towards my dilema Feel free to say anything at all. Thanks everyone!!
