Still very desirable. I regretfully sold my 153 block last year, but waiting to have one built and getting the parts is no different than what V8 guys are going thru currently with aluminum heads. Hard to tie up that kind of scratch and wait a year to be built.
Odd fire?? LOL. Early days of the turbo scene.. odd fire bow tie with a T72 ball bearing, Th400, and a 9”… lol
