I went with a 3.23 in my 340 Challenger stroker. It had 3.91's in it but I swear I could have went with 2.94's to make it cruise easier. Course it put about 430 on the ground. Plenty of torque. Stroke made a big difference in it.
I still remember the last ride in which he rode with me. I parked the car for years when he passed and still have the picture of him sitting in it which was taken of him.
DMT has them.
