This is what info I have.
14015445...454.......78-90...2 or 4 bolt
And I have pulled the pan and it is a 4 bolt main block, here are the heads that are on it as well
14096188...70-71...rect...OPEN...454 service replacement, also used on later Mark IV LS-6, LS-7 and 454 HO crate motors, 116cc chamber
I believe that 116cc chamber size is incorrect, I believe they are 118cc chambers
