And I'll say it AGAIN.......what kind of "performance" engine build uses cast pistons .050 in the hole and a cam so small you dont need valve reliefs?

True..... But!!!....
What kind of “Class” in racing would require stock pistons? Ether today or yesteryear?
As mentioned above.... the super right on budget would seem these kinds of tips and tricks.
In my head, if I had to run a stock piston & bore size, then the cams I’m looking at are low lift.... stock-super stock class type cams I think. Long duration and stock lobe lift.

Only thing I have to say is, junkyard engines are already loose so it would still be a waste of time flipping pistons in one.

True for the “LA” engine, not so much for a Magnum engine, mileage dependent maybe? IDK!

All in all, a good used core is going to be a Magnum IMO and I think you could build quite a runner with the base long block.
