    Well Keith, we ran the same basic engine at Bonneville. My guess is that
with new heads your Dyno sheet is way off. We ran 8500 with our motor, and
Mikey liked it. Unfortunately you really need a gear in-between the 3.07 and
the 3.25. With a QC you have five more choices between your two sets. Were
running a 3.12 to start off in the Chevette.

John (were gonna try for 200, maybe we can get in a magazine too) Beckett
