What is a good rear gear to start out with? I have turbo 350 tranny.

If you run 1st gear in your 350THM a 2:73 rear will give you about a 6:88 final drive, a 2:23 rear will give you about a 5:62 final drive...................................
If you run 2nd gear a 3:73 will give you about a 5:67 final drive and a 4:11 gear will give you about a 6:34 final drive.............
It really depends what rpm your motor makes the most power.................

A 4.11 ring + pinion with a turbo 350 in 2nd gear, is more like a 6.16...a good starting point for Thriller. I have a set for a 7.5, if you need them.

I would like to purchase your 4.11 gear if possible. I have a 7.5 rear.

Second gear in a normal 350THM is 1:52 to 1.........do the math=6.2372 final drive.......................

Wall loves alotta gear outa the turns, if you have the right sneakers..................
3.73 to 4.11's should work for ya, you shouldn't have to drop below 3500rpm in the turns...................
Good Luck, see ya there...............
