Carb spacer dyno test
A few weeks back I promised a carb spacer test along with a water temp test. Performer RPM air gap, 770 CFM holley carb which pulled 2.4 inches of vacuum @ wide open throttle, the spacers tested were 1 inch 4 hole, and a 1 open spacer. Water temp tests were done at 133 degrees and 158 degrees.

Why is it so lean? You're going to burn a piston if you keep that up. It's more lean when the temp is lower.
