A: I know about the steps in the cyl but I was thinking of extending the 
sleeves 1/4" or so below the bottom of the bore so the pistons didn't slap 
from extending so far. I have been told by several sources now that the 
cheap stroker buildup (ie: 4.0L pistons and block with 4.2L crank and rods) 
doesn't last long at high RPM because the piston goes so far down the bore 
the skirts come out and it "rattles" in the hole till the piston busts and 
it jams. (making a horrible mess from the one I saw so far) Longer rods 
would also cure this issue, but then going with Accurate Power's pistons 
that work with the 4.0L rod would cost less anyways!

You don't' run longer sleeve, don't know who you talked to. You over bore
the cyl almost to the bottom, you leave a ledge at the bottom, that holds
the sleeve in the block and keeps it from being pulled down and out of
the block. Also the bottom of the cyls are to specs, if you ran a longer
cyl sleeve, you would then find that your rotating assembly would hit.
The head holds the sleeve in at the top.
