I can only find two intakes for TBI motors. One is a Holley, the other is G.M. Performance w/ Vortec heads. Would a 1/4 in aluminum plate with the TBI positioned in the center work well ? Or is there some black magic involved in the placement of the TBI on the manifold. Or is there an issue with plenum volume ? I can find at least a half dozen smblk intakes w/egr but they are all for carbs. A trick carb spacer-adapter plate may give many more intake choices.
