Looking at this 360 on Craigslist - Questions

catalytic convertors came along in Mopar Exotica in 1975......

Hippy - Disco people were strapped to the gills to get by and pay bills during the Gas Crunch....much less change oil/spark plugs on proper maintanence schedules.

The 80's were no better....EPA mandates, vacuum hoses, electronics....stupid smog air pump crap.

There is nothing physically wrong with 1975-1988 engine blocks, or heads......

Its the fact they are usually carboned up, dirty, poorly maintained, and smog-era to boot.

I would want an engine that wasnt produced during the worst time of smogged down performance, block Core Shift, and lackadasical factory performance enthusiasm.
