I have had that cam in my 340 for 15 years. It is a nasty grind, but my combo works well. I have a PTC converter that flashes / stalls around 3500-3800, and a reverse manual valve body. My compression is very close to 10:1 with iron heads. I have 4.10s in the rear.

I'm turning 4,000 rpm on the highway at 70mph, but it still makes me smile!
