I thought about a old lakewood. A buddy has one but hes gonna use it.

They only made 1 mopar big block 4 speed truck bell housing. its the same old wide 4 pattern from the 62-93 NP435.

they never used the overdrive 833 tranny behind a big block in a pickup that I know of. if they did this wouldnt be a problem as its the same as a car bell housing, so this is the only bell housing ever used behind a big block in a pickup.
