if you're trapping 104 now, i'd expect to see a 105+ out of an aftermarket converter...coupled with your gear and a 4k stall...maybe a 12.6x at best given that mph. you'd need a tune to take full advantage of a stall that big.
my stock 273 full weight car with a only a lid, 4k stall and 273s went 8.1 @ 81 with 1.70 60'. i added 373s, full exhaust, an ls6 intake and tune and ultimately went 7.6x @ 88. VERY low 12s in the 1/4. like i was a haircut away from an 11 sec pass in da above 2500'.
