Just stumbled on this while googling something else. .
I'd expect some of you know this fella Steve Shreffler and skimming his words see one of the ZL1 'Vette motors passed through his hands. .
Seems up to date as of today w/ lotsa' good stuff noted for sale also he's interested in someone purchasing the whole lot at a package price. .
