I use my Silv-O-Lite (paper) catalog frequently. It has a very extensive listing of piston applications, with detailed dimensions such as bore diameter, available oversizes, compression height, piston pin dimensions, etc. Most applications also include standard and metric dimensions. Ditto for the Federal Mogul #115 shop specifications manual, for bore, stroke, crankshaft dimensions, and a lot of other internal engine measurements. Add a calculator and some math skills and the sky is the limit! The AERA (Automotive Engine Rebuilders' Association) publishes a series of shop manuals for connecting rod, cylinder head, and engine block specifications. Used editions of most of those manuals are available for purchase on Ebay pretty frequently.
