It was raised earlier, but as I see an in-car piston swap; what did you do on the honing pattern of these 100K sleeves? Roundness still within tolerance??

A simple ball hone to clean them up. Then checked with a bore gauge. 
if it pops it pops. It took 98k miles of abuse so far and nothing retarded happened. amazingly enough

gm speced cams. in short, what bmw does with the M series engines. they find the best of the best and stick them on a shelf and use them for special purposes. in gm's case. the T/A and grand am series engines.

from what i gathered, they ran "stock" spec cams. if they were pulled and checked, they would come out to be within spec for stock cams you buy off the shelf. just on the larger side of spec sheet.
