Re: SBF Gear Recommendation Please
 

What is the weight of your car? Mine is 3355. It's a 68 coupe.

Last pass of the season I drew a 2016 Cobra Jet at 9:00 am in perfect conditions. Couldn't judge him with a 3 second lead and twitched off the gas at the 1000 foot mark. Blew by me in the traps but I got a 12.64 at 116 with my foot of the gas.

I stall at 3000-3200 too. I tow the trailer in my avatar to and from the track. Want to ditch that if I can find a truck/trailer rig for cheap. I put enough slack in my Caltracs to slip a quarter between the stop and the spring. It helped the launch. Best 60 foot was 1.81 on bias 26 x 10s.

I switched to a Weiland Stealth from an Air Gap RPM and like the results. My 600 cfm Holly DP is on a 1 inch spacer. One of those 4 hole into 2 hole deals.

I have gear calculators, spreadsheets and various geeky stuff (and a bunch of time) to figure speed through the gears by transmission, rpm and differential ratio. Post or PM me with your trans gear ratios, shift points, desired peak RPM ranges and a list of gear ratios you are considering and I will run the numbers if you want.

Good luck on your gear hunt.
