Who says a p/v isn't in Dommys silly......A friend goes 7.80 in the 1/4 w/a p/v in his carb......Unless the adapter and manifold are blended, I don't expect crazy gains but if you did, you'd be amazed but then I'd go straight to a Dommy manifold w/a spacer.....
Dom, I did not know that. Maybe one of these days I’ll talk to an expert 😄.
