trying to identify aftermarket 340 Pistons

The engine hasn’t run in over 20 years . The engine had lots of problems, wiped cam lobe , low oil pressure, damaged main and rod bearings. i’m weighing my options because the engine i built when i was 17 is probably not the engine i want when i’m 48 .
I’m trying to figure out what i have before i go buying parts. i’d rather not use any modern aftermarket parts because of the lower quality of the china parts that’s out there now a days.
I’d prefer to find .030 over chrysler pistons get it re balanced and put it all stock .

If the motor had that many issues, I would suggest having the block checked out first to be sure your bores are still true and .030 replacements can be used. Nothing worse than assuming and then having it all go wrong.
