Bottom line. Seller listed it as a '383 Chev with less than 300 miles on rebuild'. Also was supposed to have 'tall geared transmission'. Neither.

Thing was running incredibly rich and using 1 qt per 100 miles. Compression all over the map. Tried the obvious things, but gave up and took to a pro who tore it down.

It's a 305 that's .030 over (310ci??). Looks like a fairly fresh rebuild with good parts, but wrong valve springs, so cam went flat. Lots of metal in oil, needs new cam, springs, rings (never seated and cylinders glazed), bearings, oil pump, valve job, and several yada yadas.

Seller is a licensed CA auto dealer, I have copy of ad showing 383 and transmission mod's, so am confident he will get stuck with at least part of the bill if I go to court. But for now:

My wrench says he can put it back together just fine , but advises I go to a crate 350 for about $1200 more. 383 is out due to 901 transmission. It would be nice to try to stick PO for a fresh 383 ($2500) tall geared tranny ($3000) and ~ $2000 for installation, but don't really want to go that far.

305, 350, or the works??
