Re: 1971 Buick 455 GS F/SA G/SA Build
Thanks, I have tested Aug 19. In F/SA trim I ran 11.40 with zero tuning at Pueblo Colorado 4800 feet elevation, 25.10 baro, 7240 DA, .9508 correction, running the Turbo 400 with 4.10 gears. My next change is testing different carbs, a metric trans and 4.30 gears along with a rear end redesign. I really wish I had the time to really get after this combination I think it could really run.

The index at Denver for F is 12:60 would have been #1 qualifier at the last national with that run.

The F/SA index for Pueblo should be around 12.46 a run of 1.06 under at altitude is very impressive!

Re: 1971 Buick 455 GS F/SA G/SA Build
I don't know the index in F for Pueblo, although the NHRA correction is .9508. 11.4 X .9508 = 10.84 not earth shattering.....but I'am just getting started. Stay tuned.

11.40 / .9508 = 11.99

Re: 1971 Buick 455 GS F/SA G/SA Build
Dwight,
Hunter was taking his run back to sea level with the .9508 factor. That's what that factor does. You divided instead of multiplying. As an example, the factored Index for Pueblo, 12.46 x .9508 gives you the sea level Index of 11.85. Lots of people who aren't "altitude runners" get these factors all confused. Jerry |

I thought the index was 11.40 and was translating to the altitude factor. If the uncorrected index is 11.85, then the altitude factor is 11.85 / .9508 = 12.46
