I've just discovered some not-so-nice prices.
Pistons are about $450 each for std or 1st oversize, 2nd oversize is NLA.
big end shell set is $320
mains are $180
thrust bearing is $140, and only 4th repair size is available.
block gasket kit is $407.
Add to that head gasket kits, chain, guides, tensoner for another $300 or so, and lots of engineering to fix the block, get the cam pedistal to head interface problems sorted and this is adding up a bit.
