Re: Need Gear Recommendation
what type of converter?
Looks like you ned about .15 just in 60' 5.38 won't help that much |

Re: Need Gear Recommendation
Sounds like you're close, but try short shifting it about 6500 and seeing what happens. I usually don't turn a 327 that high through the gears. 5.38's to 5.13's isn't that different-5-7 % or so. You do need 60 foots in the 1.55-1.58 range, though. What class are you shooting for, and what index?

Re: Need Gear Recommendation
Yeah, the 1-2 shift probably needs to be about 6200-6400, at most.
The 5.38 will help if you swap to a 2.52 low gear, what's going on here is you have way too much drop between 1st and 2nd, the car is not moving fast enough, and the RPM drops too far.

Re: Need Gear Recommendation
Think Mark is on it...converter or something else needs to be addressed. That 60 ft has to get better regardless of which index you're after.

Re: Need Gear Recommendation
Carb tuning is a big factor as well!

You have a good converter and the gearing is not that far off.. 60 foot time is pretty slow....and RPM at the finishline is low....as is your MPH, and gearing it up is not going to help.... Either your motor is pretty weak or it is not tuned right....
