Not sure what to think about going through the engine. My thoughts right now are to get it running. If the engine runs fairly smooth, does not have allot of blow-by and has good compression then I would probably just leave it alone. The head was already redone(valves were stuck). This winter or spring of next year I want to pull the body off and work on getting the rolling chassis cleaned up and rebuilt(new paint, bearings, seals). At that time I could redo the engine. Couple questions regarding potential rebuilding the engine. I don't know much about babbitt bearings. Can I rebuild the engine with out needing to redo the babbitt the bearings? Can I use newer connecting rods that have replaceable bearings? If I did rebuild I would probably be better off using aluminum pistons? Up the compression ration? What pistons would you recommend? Where would I get some? Any other suggestions concerning a rebuild? I want to keep the updraft carb for show purposes.
