[Fot] groov-O-matic

[Dennis DeLap]

AMICI - today the box from ISKYracing cams finally arrived UPS.  I was very excited!
  My groov-O-matic was finally here.  I had decided awhile ago that I was going to O-ring my own piston liners for my next engine build.  So over the course of the last couple of weeks I put an old race engine up on the stand and took it apart.  I've been measuring, honeing, cleaning, thinking about chevy rods, making trips to the machine shop, but really wanting to make some grooves.  I open the box this afternoon only to find no groov-O-matic, but instead some other Isky part with a very similar stock number.  Wow - did I freak.  A call to Isky eventually got me to Ron Iskenderian and the promise of a Friday groov-O-matic and a free T-shirt shipment via UPS.  Life in a small midwestern town!  Whew!
   
  I would like some help from the group on a more important issue - How sloppy can we run these 87mm piston liners.  Tell me - how much do you guys take off of these liners in a rebuild situation. 4 thou too much?  What's your take?
   
  Thanks
