No Denny, I might be wrong, but that 575 weight is for a complete engine. If you take of everything but the block and heads it should be about 125 lighter (a guess). I order the replacement long blocks at work for marine repowers, and on a pallet the long block comes in at 525, including the pallet and crate.

The website is a little confusing because he includes both complete and longblocks in the chart, but doesn't really specify which is which.
