Had the same problem years ago with a rebuilt 340. Ended up being that the engine had one factory oversized lifter bore! Check the front of your block to see if it is stamped with (I believe) a diamond. If so, you will need to bush which ever lifter bore(s) back to standard size inorder to use your lifters.



thanks, there were no symbol stampings on the block when he had it hot tanked before the rebuild.
