So I guess that is a Cliffenhauser intake then?
It is correctly identified by 67pete300 as an offy of course.
Super car, there are probably many stock Nova's heavier than that stripped 230 Chevelle. My Gonkulator puts its 250 at about 205hp, with another 30hp waiting for the Langdon dual iron exhaust.
Thanks Tom for the link, I did not know about Bangshift.
