Dragster Gears
I recently bought a 01 228" S&W hardtail dragster which had a 555bbc in it and has 33-16-15 slicks and a 4:10 gear.What gear should i put in it for a sbc,1/8th. mile only.I was thinking 4:56 or 4:88,Thanks

It depends on your motor combo. I was talking to Dan Phelps this weekend. He tries 4.30's and 4.56's with his sbc combo. I believe he said 430 was the motor size. He saw little to no difference from the 4.10. From my readings, anything under 400 inch, you will want 4.56's. Anything above that you can get away 4.10 or 4.30. The sb2.2 stuff is a different story.

Ive still got the 1.76 gearset in trans.For 1/8th mile and that tall of tire think a 4:88 would be better?My Malibu with a 4:86 went through the 1/8th at 6600 ,5:29 gear it went through at 7000.

My car was set up for 1/8 mile when I got it and had a very similar motor to yours. My car had a 4.86 gear in it.
If your going 1/8th only that would be my sugestion, but when I went to the 1/4 mile track I hit the 7200 chip at about 850 foot. Still coasted through to a 8.96 @ 101 mph....lol
