I would like to know so I will get accurate reading on my EBL Flash [for the MPG]

80 lbs is later big block and part number marking GM 1708430 or GM part #17112560
Earlier BB is par number marking GM 5235231 GM part # not listed in reference I found.
A third BB injector exists at 45 lbs (1995-1996 high pressure TBI).
