Because I'm putting my 3.8 carb'd draw through buick turbo on my '67 200 I6 as a draw through, I need an adapter to bolt the turbo outlet on to my intake, the easiest way I see to do it is to get 1 of the holley/webber rectangle bore adaptors that I think have a big enough opening, then bolt a peice of steel on top of that, cut out with the right hole and bolt pattern for the turbo, this sound good?
