390 Pistons
So im freshing up my 390. i took it apart today and found out that it is bored .030 over but it looks like the pistons are the cheap, low compression rebuild kit pistons. I was wondering what would be a decent set of pistons to get that would bump up compression to probably 9.5 to 10.1 range. I'm not looking to spend no more than $200 since i'm on a tight budget and this is not a race motor or anything. Its more of a street motor that gets mudded sometimes that needs a lot of down low torque than high rpm's.

Go here:
Keith Black Silv-O-Lite Cast Pistons - SummitRacing.com
Silvolite cast pistons with a flat top. These would be the same or similar to a '66 390 regular fuel 2bbl, which was, iirc, 9.5
This will also depend on cc size, head milling, block decking, gasket and a couple of other items.
Basically, you are going back to 1960s car pistons instead of 1970s light truck pistons.
