Default 373's or 410's for blower application?

Im getting ready to throw a D1 procharger on my 9:1, full forged 383 LT1. Ive heard that with blowers and nitrous, 373 gears would be a good choice. (I will be putting the gears into a 12 bolt). Can you guys help me out?

M6. Do you think I can run 4.10's with a tall tire? I like driving the 4.10's on the street alot.

Right now i have the stock 10 bolt with 4.10's. Ive never taken it to the track because i dont even want to know what this thing will run without the blower. It would prolly make me depressed. But im guessing mid 12's.

I installed 3.73s into my bf's s/c formula (500+ hp). They seemed to be the perfect gear for the car. It is an M6 on drag radials...he lost a solid half second in the eighth, it was quite impressive.

being an m6, i would suggest 373s. less gear = less shift, which = more time to let that bitch PULL!

Yeah I am thinking 3:73's or even 3:50ish gear with 500+hp JMO.

You should run 3:42's...........but if your asking between 4:10's and 3:73's? go with the 3:73's. I think this was mentioned earlier, but it all depends on the power your going to make. Get the car dyno'd and then figure it out. There is a guy I know who runs a 346ci with a turbo and runs 10.8's at 129mph with 3:42's. Most of the guys running big big power run higher gears (3:15's, etc.)..........FYI
