Inliners International Forums General Discussion Blown and Injected TBI Manifold question

I am looking at doing a 4.3 TBI on a chevy 250 that is a conversion in a 67 Landrover NADA. As far as the manifold goes, is it possible to make an adapter to go straight from the throttle body to the original 1 bbl intake instead of buying a new offy or clifford intake?
