  1. I am having, a complete engine rebuild, machine shop has called me about, a drop around each cyl. like 25thousand, it very narrow between some of the cylinder’s. Should the block be surfaced to make the block level to take care of the drop around the cylinder’s The drop I am speaking of is like the cylinger liner is below the block and it is the same on all cylinder’s. Thanks for any info. you can give me.

    • Ron: I just sent you a message. The undercut in the engine block is typical for engines starting late 1972. It requires a different head gasket. The undercut is about 0.015″ and is normal for later year TR’s (like Mine)
