I just bought the Magnum 2.66, but I had the overdrives changed to .74 and .50.
My thinking was I should have a similar motor rpm as new corvette at 70mph, about 1500. The 2.66 should give me a little more first gear (than the 2.97).
So with a 335/30/18 I'll be at 1650 or so rpm's at 70 mph with a 3.70 rearend ratio.
I hope I got it right!
