Small block or big block in a truck?

I agree with Rusty, the slant is an all-too-often unloved option. I have a 383 I could have stuck in my 82 D150 but that slant kept winking at me until I rebuilt it. I have the same 4-speed OD trans as yours. It's a hoot to drive. It isn't going to scare anyone, but it gets around town nicely and in OD I'm barely idling at highway speeds.
