What BB A-body traction problems do you have?

Hemi Superbee. Come on. Of course that car deserves a 4.11 Dana. The 512 doesn't have the HP. It has the torque. I was going to use an A-518 with 3.91 or 4.10 gears, but running the car through Drag2003, the times with the 518 and low gears were very close to 727 with 2.76 gears. The only way the low gears were faster was if I ran super wide slicks and drag chassis. This car's only going to weigh 3200# with me in it.
