FWIW, being a stroker has nothing to do with boost. Manifold pressure or boost is an absolute measurement of how much pressure generated by the supercharger DID NOT get into the cylinders. The longer the camshaft duration, the greater the overlap and the better flowing the cylinder heads, the more generated flow will get into the cylinder (and some right out the exhaust) and the lower will be the boost pressure reading. Thus, a reading of ten pounds of boost on factory heads, intake and cam will usually generate less horsepower than six pounds of boost on good flowing aftemarket heads, intake and camshaft. With the performance heads, intake and camshaft, more flow generated by the supercharger can get into the cylinders and less will be left trapped in the intake thus giving a lower boost pressure gauge reading.
Bottom line, ten pounds of boost will be all your 383" will want on the street. You will need a top-of-the-line ignition with good boost-retard program. Spend the bucks on an MSD or J&S Safeguard, otherwise ten pounds on a stock distributor is a death sentence. Racing is a whole different discussion, but it does not seem you are going there.
