I have read the topics which clarify the Z motors as a basic motor with Z/28 parts. I do have a question as to blocks I have seen for sale stating a Z block and some say a tall distributor boss can someone shed some light as to what this means?
Jim
i think what they are saying about a tall dist boss is under the intake where the dist passes through lifter valley of the block to connect to the cam is taller than a normal block.somebody correct me if im wrong on this
That's a big block issue, not small block. Early and late BB's have different dist bosses under the intake.

thanks jerry wasnt sure if it was on the small blocks too learn something new everyday
The 3862194 oringinal 283 block in my wife's 1966 Chevy II has a tall distributor boss. Within 1/2 inch of where the center of the intake manifold sits.
Here's a picture of that 1966 small block with the tall distributor boss before I rebuilt it (sat in the barn for several years).
