They are like hens teeth. 401s are far more common and are basically the 390 with longer stroke / taller deck (343 is to 360 as 390 is to 401). But even the 401s are much harder to find than 360s.

also,they have a non-compatible crank flange,as they ran the B/W automatic in those days. the T400/TC727 torque converter hub won't fit.

390s' were high compression,they'd not like todays gas.

i thought i read long ago some very late 390s' had the newer flange......?

They're worth far too much to the AMX, Rebel Machine and SC/Rambler guys. If you had one, you could sell it and help finance a nice 401 or really nice 360 and you'd never know the difference from the driver's seat.
