What kind of engine "treatments" do you like?

Specs for the new engine will include good forged internals, aftermarket heads, the standard stuff...I hope to be able to rev the engine to 6,500 RPM's on a regular basis without worrying about it self-destructing.

The sort of "treatments" I am asking about include things like nitriding the crank, "teflon" coating the pistons, that sort of thing---and I am most assuredly interested in learning about the multitude about which I am unaware, as well. Not looking for advice on which brand of crank/pistons, that sort of thing.....unless there is a "treatment" you recommend that is only available on a specific brand of equipment and is not available in the aftermarket. I'd also appreciate an explanation regarding why you recommend a specific treatment so that I understand how it will make the engine more powerful/durable .

Thanks in advance for whatever helpful suggestions you can make!

When i worked for the navy we nitrided several different weapons parts, i never was sure exatly what it did except deburr and maybe harden and close porosity?
Does anyone know the complete answer?
We also used lots of phos coatings and teflon, also glyptol paint inside gear cases etc.
thanks

post #3 above has a link to comp cams nitriding info page. there is also a pdf download on the comp cam info page for more detail. For non- roller cam applications getting the nitriding treatment seems to be a smart move.

The Navy did not use that process, they submerged the parts in nitric acid for a measured length of time and rinsed several times, thats all.
Also used saline solution with dc current to de-burr and do some machining in late 60's.
I think industry has adopted some of this also.
I remember a beautiful piece of work, a 40mm machine gun barrel. bright chrome inside bright black chrome outside.
We found that out of all the coatings we used, a very light [flash] coat of zinc chromate prime coad with a proper coat of paint was the most important for the exterior protection.
The phosphate coatings are very good under paint or for a lubed surface.
