A friend of mine recently built a 273 and used an NOS one of those intakes on it. He used around a .450 lift solid cam in it from memory...along with a couple 500 cfm Carters.. It's just a cruiser engine going into a Ute
(he has about a half dozen small block dual quads saved up think one is going to go onto a 340 he has eventually too...just for looks more then performance really)
