273 Cylinder Bore .004 over spec

Plus what are the pistons at? How much coating will it take? Even if you coat everything, the block still has to go to the machine shop to be honed back round and get the taper out. How much is that? Plus the coating? 300 bucks huh? Even if it's 1/8" thick? While coatings have their place, like temperature control, IMO (again, IN MY OPINION) they are NOT for taking up sloppy clearances. What's it cost to hone a block correctly back round (and now way out of spec)? 350-500? So now, what could you have done correctly for 800? Put a little more with it? Look guy, if you already knew you were gonna build a sloppy motor, why did you even ask? To get just THAT ONE person to say "yeah, try this"? Why did the factory even use specs at all? I guess we're all engineers now.

You need to go read up on the coating.

I know exactly how much they can cost and it will have better ring seal than if he bores and hones the block.

The next guy can bore it.
