Please help me ID this engine. From my internet research looks like a 67 440 non-high perf engine with 0.020 oversize pistons. Any other info from the other symbols would be helpful. Thx

What 440 is not hp? Even the 78 440 was the highest performing engine Chrysler had that year.
All 440s either had a 4 bbl or a 6 pac just like all 340s.

You engine should have closed chamber big valve heads. (915s w/2.08 intakes)
 
Look in the shop manual. I don't think 020 means piston bore it likely means crank undersize There's a section in the manuals showing the block markings etc

The research I did shows it has smaller exhaust valves than the HP version of the engine. And a different casting number on the heads.

They had different cams for std and HiPo 440's. Also, even the 915 heads came in two flavors with HiPo versions getting the bigger exhaust valve. Curious if the OP knows what the head casting numbers are??? If 915's, look for the HP stamp on the END of the head. Bet it's not there.
