More info, where you make power, the rest of the combo trans and such would help..FWIW my Hemi was in that power range with a 33" tire and a glide and I ran a 4.30. Car went 8.70's at 155ish that way and I crossed the stripe at 7050. Oh yeah mine was 2920 with me and the Hemi on board.

Then 4.30 sounds like a good choice to me.

I was thinking with the TF a .30 might be a better choice. But if you were thinking like a super stock racer then 4.88 might be better, the car will likely be quicker with it, just no as much MPH..Must be the bracket racer in me again.

I'm likely leaving a little bit on the table, I run a 4.10 with a 33" tire. 3000#, 850 hp. I stayed with the 4.10 since I hope to hit it with a little spray in the future. It's done a best of 1.25 sixty but more typical is 1.28 or 1.29 I took out 4.56's when I put in the new motor so I never tried it with any other gear. I have no suggestions since I've never tried any other gear, just providing info as a point of reference.

I run a 4.56, 33.6 tall tire, torqueflite, 3000lb car, cross at 7400 rpm. Max hp at 6900 to 7000 rpm. I have 440-1 heads, so power is likely to fall off quicker than a hemi?
8..603 156 mph best, 2905 lbs 549, indy 572-13, alky
