I was surprised to find valve reliefs in the pistons from an engine of this era.A '74? Good thing you aren't trying to save those pistons then...I think the compression ratio on the mid 70s "Smog Dogs" was like 8:1...good for 20+psi of boost....but not for anything else.
That looks really bad. Do you know if it was sitting outside with the carb or intake open to rain?Finally. Not a single bit of this thing came apart by hand.
Not sure. My buddy said all he knew was that it came out of a ‘66 coupe that was purchased by a friend of his. I got it for free, so it’s no big deal if it’s junk. I still have the 302 I got from the Pick-n-Pull last year if I need it.That looks really bad. Do you know if it was sitting outside with the carb or intake open to rain?
Run a set of stones through it and see if it cleans upThis is the cleanest cylinder. This doesn’t look like cross hatch, but it looks a little too uniform to be rust pitting? I honestly have no idea. What do y’all think?

I don't have a hone, so I'll have to get one. Never done that before.This is probably the best advice...but chances are if you want to save that it needs a bore at the least.
