I have a 1970 Charger with a 440/493 mill. 10.8 to one compression, Edelbrock 84 cc heads, 2" TTI headers with a full 2.5" exhaust system. MP 292/509 cam. 727 with a 3000 stall converter. Car is 3850 lbs + driver. I had been running a 4.10 in the 8.75 axle for years but recently swapped in 3.23s for the summers car show season. Eventually I intend to install a Gear Vendors unit.
I took the 4.10 chunk in to my axle guy because it had some whine to it. If the gears are going bad, I will possibly change the ratio. I like the idea of going with less gear, but I dont want to lose much of the "out of the hole" punch. Mopar Actions Road Runner also has a 493, and they were able to squeeze high 11s with a 3.23 gear. Testing several ratios would take too much time and money. Any suggestions?
