Not trying to sway anyone on which set of gears to get...Day 542
... the tipping point for me was the cruising RPM at interstate speeds………at 80, the Corvette RPM is 2000. With the .76 the SLC it will be ~1800, and with the 1.038 ~2500....
But everyone should keep in mind how their engine is cam'd vs a Corvette. *IF* you have a wild cam, and don't have ITBs, an 1800 rpm cruise would be a nightmare. It would buck and jerk, and the light weight of the SLC would probably make things worse.
I have no personal experience with the crate engines most are using (other than LS7), so I have no idea where their cams fall. But I have had a wild cam street car and it was unpleasant under 2200 rpm with light load.
Changing the gears in the Graz is a PITA, so hopefully everyone makes the right choice for themselves first time around!
