I recently scored a 1968 440 HP block. The top rear near the oil ports shows "8D235xxx".

This should be the last eight of the VIN of the car it came out of, but I expected it to start "8A" (Lynch Road), "8B" (Hamtramck) or "8G" (St. Louis) and mot "8D" (Belvedere, IL).

What 440 HP would have been built at Belvedere, IL?

Thanks!
