Hi Heath-there is little information available on most Continental engines-you can look under the Technical Page-Fuel system-Zenith Replacement Carb Chart for basic specifications. Also look under Durantcars-Flint-E55 for more description. Also under Manuals is the 1930 Continental manual for rebuilding engines. Egge in CA does pistons and Olson's in WA does gasket sets. I don't know of any other sources. Hope that helps a little-Phil
The Durantcars link only shows 500 E-55 Flint cars made(the only Flints from 1923) I'll bet the info from the later E-55 listed would have similiar if not the same engine specs.
