Recommendations for final drive ratio and tire sizes for a

[Askotto@aol.com]

Ok list, here's a real LSR question.
 
We're building a 32 Ford C/GR and were wondering if anyone has ballpark  
figures for what gears to run and tire sizes.
 
It will make somewhere under 870 HP and run a 4 speed manual trans.,  
Chrysler 8 3/4" posi rear end.
 
Thanks in advance.
