whats the best way to check for previous owners mods done to an engine?
Car i've got is a 69 with a 1978 305 in her. Prob only 145hp although seems like alot more.
Heads are original, air intake changer to a edelbrock performer and oil pan changed.
Car seems too zippy for the engine to be completely stock. Driven a good few mid seventies vettes and they all seemed way less powerful.

I can't think of a non-invasive way of checking the pistons or compression. Perhaps a compression test would give you some indication but not much more.
One thing you could do is degree your cam. This would give you an idea if it is stock or not.
