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.
I was surprised to find valve reliefs in the pistons from an engine of this era.

I’m thinking they may not be original. The heads have “289” cast into the valve area. My buddy says this engine was pulled from a ‘66 coupe. I need to take a look at the piston I removed so far for any markings. I removed it with a length of tubing and a BFH. I may need an air hammer to get the rest.

I’m thinking it was a V8 conversion that it was pulled from. No other way to account for the hodgepodge of parts.

Finally. Not a single bit of this thing came apart by hand.

That looks really bad. Do you know if it was sitting outside with the carb or intake open to rain?
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.

This 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?

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

My plan was to take it to a machine shop as it sits and just have them look at it and tell me if it's a boat anchor. I still have the '95 302 next to it. I was planning to take both at the same time to evaluate the '74 302 and have them freshen up the '95 302. I don't think the '95 302 will need much at all to get it going. I was wanting to use that engine along with the GT40 heads and Cobra cam I acquired in my Grand Marquis. I just need to sort out transmission/computer upgrades. I can then either keep the '74 302 after it's rebuilt, or repurpose the Mercury's engine block for future use in the '66 after swapping in the '95 block.
