KB107 vs Speedpro pistons

If I didn't know any better, I'd think you're a 'Wise ***' RustyRatRod.

KB makes both coated and un-coated. As well as 'two' different types of Piston's.

I can see you have never installed KB Pistons in an Engine.

And I know for a fact, you have never operated a Boring Bar or a Sunnen CK-10.
