Why u want to do that? Just change out fuel pump for correct pressure one in tank. Reconfigure gas lines at motor end hook them up. Ls system is far better than the tbi gm set up.

I have a 92 Sierra with a carbed 6.0 that I run the factory fuel pump. But that Holley throttle body is just for air so you would have to get fuel rails and injectors to make it work. As stated above it would just be easier to upgrade fuel system if staying fuel injected. As for mounts I used dirty dingo.

TBI GM trucks use 16-20lbs flow pressure pump and you need 58 at the rail. My 88 truck was TBI. It was easy change pump and hook up 2 lines. 1 pressure and 1 return. Unless you have returnless rail.
