Engine Piston Suggestions

You could post up a want add in the classifieds on here and other forums as new pistons are getting pretty expensive. Do you think you need to bore the block or can it just be honed where you can reuse the stock pistons and just re-ring them?

I agree, see if you could use the original pistons.
For me it would be either all in or all out.
Changing the pistons for a 306 is more like half in half out. The block is the limit, not the pistons.
If i'm changing pistons it's most likely for a 347, maybe a 331.

For what your intentions are with it, I'd give a nod towards the Summit brand hypereutectic flat tops. They have one with an altered pin height that will put you right at, or darned close, to a zero deck without having to machine the block. I don't recall the part number or price off the top of my head, but I know they are quite reasonable, and more than adequate for your application.

If you are going to spend the money to bore a block, forged pistons are the ONLY piston to use " in my opinion"
Hypereutectic pistons are CAST pistons ........
Seems like Summit had some reasonably priced forged pistons last time I looked but this was before Bidenomics...
My machine shop recommended another brand of forged pistons he liked which I went with...

I purchased an Explorer engine to rebuild... I cannot tell you the mileage but the exterior was very rusty as if it had been wet for a long time...
Inside was super clean... After inspecting it my machine shop told me they could hone the block, polish the crank, use some new rings on the pistons and reuse it if I was not racing it or driving it hard..... Less cylinder wear on Fuel Injected engines was the machine shops comment... So this might be an option for you as you asked for budget advice....

X2 on the forged slugs, provided they meet your targeted budget. For mild to even semi-hot street, they aren't necessary, but if the price is even close, there's no reason NOT to go forged. Forgot to mention, regardless of piston material, don't skip balancing!

TRW L2482 forged pistons in appropriate oversize for your new bores.
