Will it flow enough air if cleaned up/port matched?

Kevin has essentially the ZZ4 in his car, and his best is a 13.2. I know he had a ported plenum and stock runners, and I think a stock ported base. Im sure a few aftermarket parts cant hurt though.

 

Yep, with a ZZ4 cam, ported ZZ4 heads, SLP 1 5/8" headers, and ported stock TPI intake, I've run 13.20's @ 107 MPH, and put 285 HP and 380 TQ to the rear wheels on a dyno. Dont forget the ZZ4 heads dont have EGR passages, if emissions is a concern in your area.

I get over 20 MPG on the highway, usually about 22-24. I have a friend who burns my chips. I only have to touch the WOT specs (more timing and fuel), as the idle and closed loops specs are fine.
