well how tall is the rear tire ? and how hi do you want to rpm the engine?
28 or mabey 29 I dont know have not disided yet what is a good size?
With a 4.56 rear, 1:1 trans ratio (high gear in a powerglide), and 28" tires, you'll max out at 110mph at 6000rpm, if your motor can rev that high.
With 29" tires, you'll max out at 114mph at 6000rpm
I estimate mid11's in the quarter so I will be going faster than 114 so what do you suggest I do?
So get some 44" tires...mudbogger/drag racer!!Quote:

Smaller rear end ratio, much larger tires, or a transmission with an overdrive. Go to www.bgsoflex.com and click on "rpm and mph correlation" or something along those lines - it'll give you a calculator that you can use to try out different combinations. I think the site is down now though, if you go here: http://clubcamaro.net/index.php?page=bg_rpmmph it's the same calculation on a different site.Quote:
