360 Cylinder Pressures

Subscribed, I hope you continue with the updates!
For what it's worth, my first small block was a 1972 360. The only real difference between it and 73-up was that it had factory flat tops, no valve reliefs, rated at 8.8:1. Never any machine work, std bore, bearing size, oem valve job, etc. J heads. Guy I got it from did a re-ring in 87', along with a Crane 224/[email protected] cam. When I did a compression test, I got 140-145 straight across. After 10 years of abuse by him, and 3 by me. It was a pig with a stock converter. Dead stop, barely a squeal. It had 2.76 gears. However, a 10-15 mph roll, I'd be sideways! It really woke up with a 2700 stall, even more with a 3100 and 3.23 gears. Ran 13.6@100 with tire spin, 2.1 second 60'
I know big cams can kill cylinder pressure. But, in MY opinion, never by that much, especially with that cam. I would still expect 125 or so if it was not worn out. Just my opinion, and I learn best when I'm proven wrong! Lol
On the other hand, I hope your cam swap solves the problem and you are back on the road soon.
