Update for my Tempest. I ran a 7.671 @ 181.59 at Wildhorse Pass at the Phoenix Drag Reunion (Pontiac Heaven) event yesterday. Density altitude was 1954'---ideal weather conditions for Arizona. It was my first pass at 10% over on the blower. I was leaking oil bad from the driver side valve cover and one of the bolts is stripped, so I was done for the weekend.
Discovered today when I looked at the Racepak data, I was on the rev limiter at 8,000 for the last second and a half of the pass. Guess I'll have to readjust that.
For George: my boost was at about 15.7#. I looked for you in my rear view mirror (figuratively speaking), but you were too far back to see.
Who needs them fancy new heads? My older than Edelbrock Wenzler Super Chiefs seem to work OK.
Jim
