Look at Harristuning.com if you want to keep the TBI system. Quite a bit of suggestions on cams and what parts to achieve different power levels on that website.

Its great fun playing on the Summit site, but easy to lose control, last time I ordered the Jeep steering shaft to do the conversion to get rid of the rag joint ( Imho one of the best things to do ever to one of these old trucks) and ended up with 20 T shirts as well

Tbi doesn't like a lot of cam,keep that in mind. TBI fuel control is based off of engine vacuum and big cams make less vacuum. If you really want to change intake manifolds most sbc 4barrel manifolds can be used some require minor changes. A TBI adapter plate will have to be used if you go this route. Theoretically switching to a good dual plane manifold should respond about the same as it would with a carburetor.

I put a link to their site on a couple other posts. Pretty cool tbi builds on there,didn't want to put their link in too many places.Because I didn't want people to think I was beating a dead horse. Anyway a lot of cool builds that get good mpg.
