4:10's a bad idea with spray?
I plan to spray 125-150 shot on the street and I have an M6. Is 4:10's gonna be too much gear because I dont want to be shifting into 5th before the 1320. Do you think 3:73's will be a good median?

Depends... if you have a cam that pushes your shift point up to around 6500 rpms, then no it isn't a bad idea.
If you're still on stock shift points & rev limiter, I'd stick with 3.73s if you're spraying.

My 4.11 are great on the street on my stock motor, BFG drag radials and T56, but I have serious traction problems with the 150 wet shot. I wish I had 3.89 r/p.

Can anyone link me to the speed-gear ratio chart? I too will go juice (100-125 wet shot) next winter, maybe with 4.10s.
My H/C combo allows me to 6800 rev limit. Enough gear for 1320 with stock tire size?

I even misshifted and spun the engine WELL ABOVE 6800 and so far no problems with the valvetrain. In fact, after that misshift, I went on to get a personal best that same night.

I'm shifting my little all stock motor at 6000 when on the spray, because I want it to last. Hell, I'm shifting my solid roller n/a 622 at only 7700 rpm! Remember, it's only got a limited number of revs in it.

Either that or I'm a retard.

1ScrudeDude - You can select the pre-set M6 from the drop-down list, but then alter any of the values in the text fields (such as changing the 3.42 to 4.10) before clicking the calculate button.

I'm good to 127 mph and I hope to challenge that I'm hitting 117-118 traps now NA. Therefore, I am going to leave the 4.10s in and go with a slick and/or taller tire. The 4.10 ratio is just too good a gear for this set up, plus, I want to maintain some digs when I run on motor.
