Lower gears and still slugish.

Running street tires. My 318 is .30 over with a eddy 7177 cam, eddy aluminum heads, eddy rpm intake, 650 quick fuel carb, long tube headers, full MSD ignition. My 8.8 is a limited slip with 3.73s. I had a 7 1/4 with 2.76s. Taking off from a stop is horrible. Looked like a stock converter, I know a good 2500 stall would help but there is literally no difference with these gears.
