Re Chrome a sleeve
I think Ed is correct as the whole process is more involved than it looks. Its really too bad GoergeAldrich passed away last year as he would do most ABC jobs for $50 and the quality of work was reported to be better than factory specs. Good Old American Chrome Plating is hard to beat.
Is there anyone now who is doing this kind of work? I see that Just Engines has a line of true ABC piston/liner sets for the 46SF and FX and their prices seem a bit lower than Performance Specialties ABC piston/liner sets.
