It's nothing special but the dang engine outruns the tachometer!
For a comparison, my dad was curious what the cranking compression is compared to a regular 360. At this elevation, 95 PSI is the max for a healthy stock 360 and a lot of the goid running ones are in the 85 PSI range. After 30 minutes or so of runtime, this one is at 135 with the other spark plugs installed (so not cranking incredibly fast). I think it's a winner!
