The logic may go something like this, they knew they were switching to all cast cranks but they had to use up their remaining forged cranks so they just divided them up and said "cast crank, 2bbls forged cranks 4bbls".



B U T ... they kept using the forged cranks in the 400 for a long time past when the 383 was dropped.

OK ...you guys with all the lists and data ....

what was the OEM weight diff between a 383 and 400 piston? ... I am thinking that back-then there was little to no weight-diff between the two pistons. T H E N ... why not use-up those forged 383 cranks in the 400's ?

Whatcha' wanna BET that they used them up that way ? .... (or should have!)

NO SCOOP this time !
