340 Rebuild Checklist

Clean, Clean and more Clean, block oil galleys and the crank passages along with the cylinders and everything else!! I use the bath tub and hot soapy water to clean the crank. Don't forget to put in ALL of the oil galley plugs! Make sure the rocker arms go on the shafts the correct way and make sure the rocker shafts go on the engine the correct way.

Before you assemble the block, check how the oil pump drive fits into the bushing in the block and also fit the camshaft into the block before assembling anything in case you have to deburr a cam bushing.
