I'd like to know if anybody has used the Sealed Power skirt coated pistons. I looked these up last night on Federal Moguls website. Im considering having the old 400 in the back of my truck rebuilt by Carolina Machine Engines. Of course to save some $$$ I will do the pistons and rings myself. The pistons have an antifriction coating on the skirt of the piston to help reduce any more friction in the cylinder. This seems like it may add to the cost but if I rebuild this 400 I want to put some quality parts into it. Im planning on having a mild performance engine that is a everyday driver but will get up and haul buns when I want to

The Summit racing hypereutectic kit I purchased for my brother's .040 over 302 had the coated pistons in it, has ran fine, but only has about 3000 miles on it(in two years).
