What do you think it could run?

Basing it on 3240 and a conservative on track 350fwhp>
60 Foot E.T. : 1.70 Seconds
1/8 Mile E.T. : 7.72 Seconds
1/8 Mile Trap Speed : 88.08 MPH
1/4 Mile E.T. : 12.23 Seconds
1/4 Mile Trap Speed : 110 MPH
1/4 Mile Trap RPM : 5,810 RPM
I would agree with that as best case scenario, but his car is near 3400 with him in it, so....12.35?
The problem is info that is missing about camshaft (hyd or solid)so no one knows powerband or ideal shift point.
Op has stated he will be happy under 13s. I think he'll be happy.
(If a hyd cam, I'd shift at 5500, solid at 5800-6000)
