What were you smoking when you came up with this brainstorm?
Ford makes several big block engines that will fit in your truck without a lot of work. If you are doing this because you want a Chevy try buying a Chevy next time. Big block Chevy engines fit right in them so you won't need a kit. I'd try to find a half ton pickup to start with. They make better hot rods. A car would be even better.
Sure it can be done but It's not easy. If you have the skills to do it you wouldn't be looking for a kit. You would know that you're on your own with this oddball swap.
Don't expect many people to think you did something good. Most of them will just ask WHY?
If you already own the bbc you should shop around for something better to put it in.
