So, last weekend of the year, and my 904 gave up the ghost coming out of the burnout box on Saturday morning. It appears that the sprag called it a day, but we won't know until it gets yanked. At least that gives me a reason to up the ante on the converter. I'll step up to one that can flash to over 5000. The current unit will hit 4700 on the t-brake, but only flashes to 4000 when I footbrake it, and the t-brake is worth a tenth in the 60' right now. What are people's thoughts on the value of a 2.74 low gear behind a 360 that makes modest amounts of torque in a 3000 lb car? I am running a 5.13 gear already, so I would think that adding 12% more gear along with another 1000 rpm of converter should really make this thing leave.
