A3 stall?

A3 stall?
Im working on a 99 z28. Cam only, a3 w/brake, 4.30 gears 28 tire and gas. What stall would be best, shift at 6800-6900rpm. I would like to leave on 150 shot, maybe 200 shot and run a total of maybe 300 or so with a second stage. Also would this setup work for the 1/4? I keep getting mixed anwsers on if it will run out of rpm for the 1/4. The car is being built for mostly 1/8 mile and some 1/4mile.

My Camaro (in sig) is 3300 with me, 4.10 gears, 28x10.5's, Fuddle 8", 150 shot NX wet, shifting at 6800.
Went 10.92 NA, and 10.00 on a 150 shot back to back yesterday. I don't think you will get away with 4.30's, and I could not spray anymore on top of the 150 unless I either went with a tighter converter or down to a 3.70 gear. With a 3.70 gear I could spray 250 and run mid 9's.

Thanks that helps alot. Whats your stall speed? Here we race way more 1/8 vs 1/4 so the 1/8 mile time is more important but it would be a big plus to be able to make through the 1/4. Do you think 3.90's on a 300 shot would make through the 1/4?
Now knowing this is more for a 1/8 car what do recommend? Should I just give up on 1/4?

30's look kinda crazy on our cars, you have to cut the sheet metal unless you are minitubbed.
I made about the same power on motor thru the T400 FWIW. You can run the 4.10's and probably go 135-138mph before you run out of gear. I went almost 134mph and I might have gone a bit faster if I had shifted a little lower but didn't have time to mess around.
With my turbo car I am going 144mph with 3.50's and 28's, with room to spare, I could go 165mph potentially with the 3.50's assuming 7100 rpms.

I think I have a set of 3.90's laying around the shop. I will try those first since I don't have 4.10's. Do you thinks the 4.10's would help it more in the 1/8? I could probly spin the car to 7,000 if I had to to make through the 1/4.

4.10's would work a little better than 3.90 for when you are on motor, but at some point you have to pick n20 performance over motor performance. Personally I have two cars that are quick so I want the Camaro to run mid to low 10's on motor for a while. But I'll keep spray on the car.
