Welcome aboard.
Honestly I wouldn’t put money into a 326.
For the same or even less outlay you can put together a 400 and nobody can tell from the outside appearance that it’s not a 326. Better yet do a 455. That’s the beauty of the Pontiac V8, they’re all the same physical size externally and all bolt in using the same mounts and exhaust (with minor exceptions).
Just the cost of the oddball 326 pistons would be more than common off the shelf 400 or 455 pistons. Just because you already have the 326 doesn’t mean it’s wise to put money into it, I’d pull it and keep it as a spare good running engine.
