So I have a 68 coupe, with a 93 302 bored .30 over, with 289 Hipo heads and a C4 tranny. Currently I have the stock 2:79 8" rear, and want to upgrade to 3.55's. The car runs great, and has a little bit of balls. But I also have a stock torque converter. So if I upgrade the rear gears will I notice a big difference in the getty up? Or do I need to change out the torque converter to? What is stall? It is just a weekend cruiser that I like to get crazy with in straightaways. Thanks for any input.
