Cyl sidewall wear with a 416

Great discussion - and yet another reason FABO is such a great resource. I have talked with the builder who thinks the indications on the cyl wall are no big deal. I think the bores are finished properly and the engine did have quite a few dyno hours.he I just wish it had coated skirts, I think.

This brings up the topic of coatings on the skirts and coatings on piston faces and the combustion chambers on aluminum heads. Do thermal coatings make the supposed 1 point of compression with alum heads go away - ie bump compression with thermal treatments?

I am on the road up near Carlilse picking up body parts for da fish. Saw a few cool Mopars at the dude's house. Life is g.ood
