Rings just plain aren't going to make up for an out of round cylinder but do what you want. If you go with the tight clearance KB pistons be prepared for some piston slap too. If you are going to spend the money for new pistons do it right. For about 125 bucks you can have it bored and the pistons fit right.
Putting rings in this engine as is is just silly , the cylinder needs the proper hone finish to get the rings to seal, I don't think gapless rings come in plain cast iron as that's probably the only thing that will even remotely seal , plus now people are expecting him to breakdown the short block while it's still in the vehicle ?
Don , I wish I could get a V8 bored and honed for that cheap, around here is $300 ...
Train wreck , that's what this has been for me ....

Typically changing pistons will require the engine to balanced as well. Otherwise its going to shake itself apart. Also the factory head gaskets were .020 and felpros are typically .042 so milling .040 off the heads only nets a .020 gain.
I think your money would be better spent on a performer intake, carb and camshaft.
Did you notice the date before dragging this CF back from the dead ?
2009 ...

Do you actually have anything constructive to add , if not go back under your BRIDGE ... PLEASE ...
I really have to laugh at this, 'constructive to add'. Funny thing is, when I said the same thing your response was something along the lines of 'people not blowing sunshine and rainbows up your backside'.
Pot meet kettle x2.
This was an interesting thread that I didn't mind reading through. So what if someone brought it back from 2009? What's your point?
Mike.
