Either way at 14 degrees and fuel mixture set up i'm getting right at 15inHg of vacuum at 750 rpm. When i'm cruising at 50-60 I'm running at 2200-2300 and not sure if that's where it should be or not. I have 3.23 sure grip rear and 3 spd auto trans.
Is that cruising at 50-60 mph or degrees on the distributor? at 2200-2300 rpm?
With 3.23’s, automatic trans and stock sized tires (or close) Id think you have oversized tires. Larger in diameter. I’d say the rpm is low. But good for cruising.
If it is timing, then I’d say 50-52 total is fine with the vacuum advance hooked up. 60 degrees would or should be a bit much on cruise timing. Low compression engine and more so with open chambered heads like more timing at WOT & cruise.
