Well the last time I checked a Compression/Cylinder Pressure Gauge was a diagnostic tool. By taking the measurements at each cylinder one can determine which cylinder(s) have pressure and what they are. One can compare those numbers to each of the others and to known acceptable numbers. (~180ish psi for a Sprint and ~165ish psi for a 1 BBl) If cam timing has been confirmed and there is no compression/psi, then either the cam tower has been excessively milled or the valves are too tall, or lash adjusters pumped up.(metering tube installed? spec oil pressure?)Too much oil pressure in these engines will cause the lash adjusters to pump up too much and keep the valves open. Was the oil pump spring pressure increased? Was the lash adjusters filled with oil prior to install? (should not do that) There are a few things that could be wrong with this rebuild, and I am trying to help this person out. During my Sprint rebuild I had a similar problem and mine did not start. I knew my valve tips were within spec and the oil pump was within spec also, so I took cylinder pressure/compression measurements and saw that a couple cylinders at the front of the engine had no pressure. The others had some, getting higher at the back. So I incrementally increased the gasket material, taking measurements at every iteration and find out that at .060" was optimal for max/even pressure readings. Started the engine and broke it in. Then I fabricated a copper plate and placed it under my cam tower to replace the gasket material. Engine made 200 SAE Net HP and 260 Ft/lbs on the dyno. Kelly please pm me so I can help you and your husband figure out the problem.
