<VV> Piston / cylinder clearances shortened story

[N2VZD at aol.com]

has anyone had issues with sealed power forged piston size versus  
markings?  I have a new set with the forged rods  (not from Clark's )  installed 
marked as .040  and  Clarks full fin cylinders marked .040 .  The pistons 
appear to only be .020 over... (showing 027 with feeler gauge  )  2 sets of 
cylinders measure the exact same. I put a used set of  cylinders and pistons in 
this motor , and problem went away. I am not used to  finding things like 
this , and am just a touch annoyed. Problem is , the pistons  / rods were 
purchased by some one else on E Bay a long time ago... 
SO with .040 over rings , this set sounds like a solid lifter cam in old  
vettes with Fuel Injection. 
I am now out a lot of extra cash over this , plus wear and tear on me and  
that motor taking apart to fix it.
  I would gladly listen to offers of real .040 good  premium cast  pistons 
and stock rods with or without rings in swap for new (run @ 1 hour on  stand 
) sealed power MARKED .040  but not , pistons and forged rods.
I can provide pictures . I also have a set of unused .040 full fin  
cylinders , one opened to measure , for sale.
More details , email me after I cool down a little.
