Re: 283 Cylinder Head Decision

Huge thank you to one of the forum members who sent me an early Christmas present of a compression tester!

I was able to sneak in a compression test today before it got dark out.

Engine was cold, all plugs removed, 3 different screwdrivers used to hold the throttle blades and air dams open on the Quadrajet.

Highest reading was 145, lowest was 135. The average was 140. That seems good to me, but what do y'all think?

Also, all of the plugs looked about the same. The past couple weeks have been short drives in the cold which is probably why it looks a little rich, but I could probably do some more fine tuning at some point. The plug on the right is the darkest one. That one came from cylinder 1

I'm just glad there doesn't seem to be anything majorly wrong internally at the moment
