One broken compression ring, either it be the top or second ring, would not be a cause of ZERO compression.
I've torn down a virgin 322 motor from my 1954 Century that's undergoing a complete restoration. After cleaning out tons of non-detergent oil sludge, the motor looks very good although I found a broken compression ring on one cylinder explaining the zero compression I had when it was running.
I was wondering if anybody in the Nailhead world had any advice for mild performance upgrades that require maybe a hotter cam or? It's a total stock restoration as the car is in amazing original condition, but I hate to put the motor together without asking!

The transmission is by far the weakest link when it comes to performance. you can port the heads, put a better carburetor on it, camshaft, headers, etc and after dumping 2 grand of performance parts it will only have a slightly noticeable difference.
Install 3.9 rear gears from a standard transmission car for the quickest perceived increase in performance.
The 322 from a 56 has at least 50 more horsepower.
A hotter cam will raise the hp and torque curve up a few hundred rpm making normal low speed performance seem like driving uphill, BUT if you combine with 3.9 gears it will work.
