Yes, you can install that Pontiac in anything if you have a torch and a big hammer, seriously, the Pontiac makes a good truck motor, you will have to use the trans that is on the Pontiac engine or buy an adapter and you will have to fab some frame mountsand possibly a driveshaft, the rest is matching up, and /or swapping parts.

 

It sounds to me like you want to see what will fit your truck, I just responded to your Olds motor post.
I won't waste any more time typing, at the bottom of my response there is a GALLERY button.
Click my gallery button to see a Cadillac 500 in my 1982 Chevy Scottsdale.
In case your still wondering about others, just about any GM engine will fit your truck.
My swap was EASY.
