i'm not too fond of sleeves i would rather have an all natural block

A lot of us would rather have a non sleeved block (i'm one of them) but in the case of my 340 I can't just find one anywere. My 340 runs low 11's in a 3200lb car with the a sleeve and no ill effects. When I was a GM I guy raced a 427 in 1981 that had 4 sleeves in it, same thing can't find 427 everywere. My buddy today (25 yrs later) has the same motor in his '70 Chevelle and is fine.

We better tell the top fuel guys to get ride of their sleeved motors or all of the sleeved aluminum block motors on the planet now and go back to iron blocks.

The the final honing will take out any distortion (if any) to the adjacent cylinders after sleeving. But let me get this right: The thin sleeve is going to distort a heavier thicker iron block and the thin sleeve won't distort when pressed in... Find another machinist.
