New life for an old 340 (stock stroke)

Yes, pistons are on the way. If you look around for a stock stroke 340 replacement piston in a 4.100" bore, you will quickly see that only one (DSS Racing) offers one. MAhle Motorsports only offers a 4.07" pistons. JE/SRP offers a nice piston but only up to a 4.08" bore size.
I was extremely fortunate to have a great contact at RWB (Race Winning Brands) who own JE/Wiseco/K1 etc........ that was willing to do me a SRP piston at a SRP price in a 4.100" size without the expense of a full custom route. << This was really the cornerstone of this whole project. J.Rob

I’m interested in putting pistons that 340 with the gap less rings I ran last summer, I was looking at forged flat tops just in .30 over as the bore on my block is good.
My J heads flow around 250 and l have the same rods and crank as you are using.... it makes me want to buy the same cam you have and see how close our engines are on the dyno...
