peecher Posted March 12, 2010 Share Posted March 12, 2010 Great! Another old 12 comes to life. Looks like you'll be using an aluminum timing gear...those fiber ones used to be a little troublesome. Link to comment Share on other sites More sharing options...
CBoz Posted March 12, 2010 Share Posted March 12, 2010 When you have the block magnafluxed, be sure they also check for cracks in the waterjacket around the valves -- this area is often overlooked. As a safeguard, you might also think about having a sealant put in the engine. My understanding is that some car manufacturers do this with new blocks nowadays. Other opinions, for or against?

peecher Posted March 13, 2010 Share Posted March 13, 2010 (edited) You will find that the water passages are a little different between the '38 and '40 heads. You may want to enlarge a couple of the coolant passages in the '38 heads ( if you use them) to match the head gasket and block. Are you using a '38 block?

Guest hannibalhann Posted March 14, 2010 Share Posted March 14, 2010 (edited) hi preacher,, yes the block is a 1938 the two heads are 40's i only have 1 head thats a 38's ,,,NEED 1 DRIVER SIDE 38"s to make the engine complete for my car, larry ps the engine that i took out was a 46 to 48 Edited March 14, 2010 by hannibalhann (see edit history) Link to comment Share on other sites More sharing options...
peecher Posted March 15, 2010 Share Posted March 15, 2010 If the crankshaft out of the '46-'48 engine is useable you might consider using it in your '38. It has larger, drilled oil passages with no sludge traps or welch plugs at the rod journals. There are a couple of things you would need to do: If you want to use the '38 style ( solid) flywheel, the "hub" that houses the pilot bearing would have to be machined off and the '46-'48 connecting rods would need to be used as they have larger bearings.
