rebuilding my l36 427,need piston advice

[VintageMusclecar]

Assuming the following:

4.280 bore
3.76 stroke
98.4 c.c chamber (702 or 390 head castings)
16.8 c.c. dome (spec for L2300)
Piston .020 down in the hole (un-decked block)
.040" head gasket
Approx. 10.27-1 compression
Change the chamber volume to 101 c.c. (802 head castings)
Approx. 10.0-1 compression.

For a <span style="font-weight: bold"><span style="text-decoration: underline">stock or very mild performance rebuild</span></span>, cast or hypereutectics are fine. For anything you're going to lean on, I would recommend forgings.

If you would like any help or advice on selecting a piston, I'll be happy to help.
