Mark, that little carb option is still rated at 274 on our car. 66 nova stickshift. I have heard from a couple racers (not in Midwest) that said the 585 was a legal replacement on the stocker 327 275 but I really really doubt that is legit. We run the QJet on that combo in stock and it works well. ( and UH OH! we actually have the product engineering bypass regulator on our car as well)
