Was 8 to 1 even an option in 69? When I was looking before, I thought 80 thou was the furthest down they would be with a stock piston.
I have no idea on the bottom end details other than it's a 69 block, forged crank and LY rods. It runs great and pulls hard so I never worried about it. Previous owner said it ran mid 12s or so, but I never tried.
Later 440s (76-up?) (Typical motor home 440) had pistons around .150 in the hole. Whatever they might have been claimed to be by Mopar, they were really on either side of 7.5 to one.
