could the intake be holding my low end down?

Well, were. That 223 cam died in 2004, and I swapped in a 230* in it's place . Now I shift at 7200. and the combo went 93 in the Eighth, still with a 2.4x 60ft lol, 325/50-15 BFG DRs this time but same street suspension,lol.

What was the ET for the 93 MPH in the eighth?
