I saw this at the Spring Charlotte Auto Fair.
VI22IMU with partial 7N160497
It was extremely rough (was outside for a long time) and I couldn't justify the $500 asking price.
Just wanted to let someone know that their original engine is still out there.
I bought this at the Autofair and found the correct heads and already had an intake, carb, distributor etc. I already posted this engine on this forum.
Here is a link to the post. It was not in the 1967 - Orphans section though.
