Here's an update to my setup as of 03/2013: I moved the cam centerline from 106 to 111. Re-installed the 4:30 rear gears, and went to larger jets in the 850 Holley carb (79s primary, with PV, and 88s in the secondaries, wanted 80s in the pri side, but didn't have them with me). In Phoenix,with DAs in the 1000' range, and 1.82 sec on the throttle stop, the car netted 154 MPH on a couple passes--7 MPH more than previous best. BTW, lost 1st round at the AZ Nationals, lost 1st round at the divisional event, went to the 3rd round at the regional event.
