What RPM are you crossing the 1/4 trap with the 3.06 final drive? It's shifting to 4th I presume?
I think even shorter would be better if you were only interested in say 0-140 mph. But, you would need LSD and drag radials for sure. Because you would probably spin a lot because of the torque multiplication of the shorter final drive.
Ideally, You want to cross the traps at the highest rpm possible just after where your peak hp is made.
