i have a steel sleeve bp with 1 nik bore , i need rings for that cylinder, for a mahle piston , a few extra pistons to choose from would be kool also. cheers.

also 625-5250 merc rods if anyone has any collecting dust or getting kicked around send them my way please. thank you.

contact pro marine for nikasil bore rings, they where the only one that had them in stock

here is a question, how do i tell the difference between chrome and nikasil ? all my bp blocks have pin holes in the coatings, i read somewhere that is one way to tell nik from chrome but i can find where or remember what was the one with pin holes.

i have pistons now, and a set of rings but i have no clue as to what bore they are for. there a solid black ring if that tells anyone anything. and 0ne single ring that came on the mahale pistons that is shiny with tiny horizontal grooves in it. i suppose my best bet would be to take my block to someone like paul and have him order me 5 sets of rings for steel bore, and 1 set for what ever my other bore is. chrome or nik, im sure a professional would know what it is if they looked at it.. i am so excited to get this thing together.

Put the rings in the bore and measure the end gap...

the end gap is within spec, more than .018 less than .024. :s but that is a steel bore with solid black rings, i really dont think its right. they should be plated rings for steel? bahhhhh
