New bracket dragster 1/8 mile. What gear would you use 4.10 or 4.30.

Not knowing your combo I would say either will work. I switched from 4.10 to 4.30 on my alky injected 565 bracket dragster and the only thing I noticed was my wallet was $1000 lighter. Converter tightened up a tiny bit but no difference in the time slip

I’d probably go 4.30 if I were starting fresh.

I have a 4.10 now but run a lot of 1/4 mile. I may still go 4.30 when I need to change it.
