Ross, Diamond, JE ?
I don't care who makes them. The only off the shelf 4.080 pistons I could find for my 340 were a couple of KB pistons, one dished and one flat top. Nothing else so far...
I'd love to have dished coated hypereutectic 4.080" pistons for my 340/418. :-\

Since you are racing do yourself a favour
Hey Dodgem - not racing with this motor - this is for my 65 Dart street car.

Dam you building two strokers?? What about the leaning tower of power?? With the clifford valve cover!! Diamond will build you what you want in two weeks out the door or less. that 9.5 to one piston would work good on the street with a mild cam.
You know when I seen eddy I thought didn't he had a couple sets of W5's?? LOL!! Dodgeboy8
Yep yep two strokers - the W5 build is for the Duster and I do have an extra set of virgin W5's that I am going to put up on ebay pretty soon. I'm not sure what I am going to do with the /6 with the clifford stuff yet... probably Ebay that too.
@dodgeboy11 - hyper pistons are lighter than forged. Forged will handle more power but I'm not building a race motor. Hyper will be a win in a street motor because they are lighter - less rotating mass.
@1965 plymouth - a lot of OEMs use hyper pistons. They are fine for street use.

here's a heads-up. hypereutectic pistons aren't built for street use and won't last. they are made for race only. my
yeeeoooowwwwkay...except just about every factory engine from the last 15-20 years have had hypereutectic cast pistons....
418 cubes, 65cc heads, .039" thick, 4.14" dia gasket, 0 deck and 23cc dish will net you 9.9:1 comp, 20cc will be 10.2, 15cc will be 10.7.
9.9 with a moderate cam (230@.050), aluminum heads and tight quench will probably run on 87 with a moderate timing curve. if you get real aggressive with spark advance you might have to bump up to 89 on warm days.

It'll be 418 ci, 63cc heads, .035" thick & 4.125" dia gasket, 0 deck, 21.5 cc dish. The CR will be 10.3 to 1... I am probably going to run the 20-230-4 comp cam. Should see about 450 HP at 5500 RPM and 500 tq at 3500 RPM. Agree?
