    322 rebuild advice

    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!

    One broken compression ring, either it be the top or second ring, would not be a cause of ZERO compression.

    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.

    Thanks to you all for your comments and suggestions. The transmission is currently torn down too. Is it is what it is or are there any tricks to improve its performance or longevity?
