The cylinder decks are fine...the machinist said that .010" would clean them up. As far as the cam bores and lifter bores, they were fine too. I got lucky there.

I kinda go along with you that a quarter sized spot may be fine...but I just don't wanna take a chance. The pics that George Anderson linked to kinda scared me. If the area was in another part of the cylinder, I wouldn't worry...but it's in a thin part of the casting anyway (close to the top) and the stupid thing is on the thrust side of the cylinder. Just my luck of course.

I think I'll just have it bored enough to clean it up, 30 or 40 over...and then make up the different with a longer stroke.

I'm waiting to hear back from Turk or Computerworks about how many original Cobras had 390's in them...hehee...
