What interconnect for engine management? First the TBI engines use swirl port heads, not known for their top end performance, but nice low RPM haulers. You need a 4 barrel intake that will fit them. You'll want an Edlebrock 2104 or equivalent see them at: http://www.edelbrock.com/automotive_..._sb_perf.shtml
This is because heads since 1987 have, at the very least, had the angel of the center 4 bolts changed from 90 to 72 degrees to the interface plane. Older manifolds can be mounted by egging the center bolt holes so they'll meet the new angle. Then a means of providing a flat, parallel place for the bolt head to mate with has to be addressed, there are commercial spherical washers to be had that are adjusted to the needed angles, or the manifold can be spot faced in the needed area, this can be accomplished with a grinder, or you can make an angle washer from a piece of pipe.
The TBI uses a computer controlled ignition, this needs to be replaced with a conventional HEI. The block has no provision for a mechanical fuel pump without a bunch of finish machining. The simple solution is an electric pump. The serpentine drive on the front gets in the way of some installations, all that can be backdated to V-belts but the water and fan have to be changed to earlier models using V-belts as the OEM serpentine stuff rotates in opposite directions.
