I run the keith black forged pistons in my stroker magnum engine...the builder did not say he had any problems with them. Mine sees some hard street miles every year and has been built for about 4-5 years now...probably have 10-15k on it..

I built a 440 with them a while back. Real nice looking pistons. No immediate issues with them. About 50 gram heavier than a comparable Ross or Diamond.
I got a smoking deal on them through summit. Like $299 IIRC.
FWIW, I'm almost certain these are the same as 440Source house brand.

just make sure that you are comparing the pistons only and the weight of the pin is not included.

Stock pins can be shortened 1/4" on each end as w 1.09" dia there is still plenty of contact area (pressed pins of course) to have no prob. And w your drill press & dremel might be able to lighten the piston. This worked fine on a stock cast piston that was raced but they are heavy & have alot of extra material to work w whereas yours may not. Just food for thought

Well the KB's are a "Stepped Dish" piston listed as 12cc? (The Diamond Piston is not stepped and yet it's still 12.5cc?) Must not be much of a step? Yet it is enough to require a bottom ring support...
