Looking For Forged Piston Recommendation

[Rocket]

I am building a near stock 340 and want to used a quality forged piston. I will be using stock X heads and a gasket of .039 compressed thickness. I prefer 0.020 over bore if available. With the fairly mild cam I will be running I need around 9.5 to 9.8 compression to meet the cranking compression of the cam manufacturers recommendation

What are your piston recommendations?

Diamond racing pistons makes (part#5001) 645$ 4,07 piston for 3.31 stroke. 60cc->9,7 cc, 65cc->9,2cr, 70cc->8,8cr. there's no many manufact. who makes stock forged pistons for 340

I have diamond forged pistons in my 390 stroker and i'm happy:-D​

I run Ross pistons. They are real light but super strong. My 340 has been together 10 years.

I think the issue you'll find is with the open chamber factory head, the typical shelp falt tops don't make enough compression until you trim the chambers down to 60ccs. That's a huge amount of milling and will require a fit-to-the-heads intake manifold. If you have to have forged, you couls go customs, which are dig bucks. Or you could use the battleship L2316(I think) forged TRW/Sealed Power deals. Keith Black also makes a hyper in that same design thats much lighter and will stand up fine for enything but NOS/boost.
