Default Re: xb et 13.10 need help to crack 12s

Some things don't add up.
The power is waaaay too low for the times.
The carby is way too big for the engine (600holley would be better)

Are you having a loss of traction on the start line? If so, a set of slicks is needed. If not, then the caltracs are not needed. The caltracs are required once you start to get axle hop and diff wind-up.

The 60 foot is really slow. Are you bogging off the line, or is it due to wheel spin?

Are you sure about the diff ratio - you should not be hitting 6,500rpm on the finish line with those numbers.

Finally, a trans brake will drop a significant amount of time off.
