Inliners International Forums General Discussion Engines chevy 250 engine block casting number

Hi Matt, welcome to the inliner's forums.

This casting number doesn't show up in the Parts Master catalogs - which just means that it was never in the parts bin at a dealer as a repair part (replacement block). Several discussion threads suggest that the casting number was used from '75 onward.

Here's a posting from a club member named Ray (#3450) Inliners Engines circa 2006 that suggests 75-85.

Further down in the posting Chevy41 posts a link to the old Butler's site (they sold reman engines). That website is long gone but we can look at the pages from the past via the WayBack machine:

which agrees with that timeframe.
