I'm not real interested in the E.F.I angle, guess I'm too oldschool plus the mods I would have to do don't appeal to me. I appreciate the links, but the Arrington price is still $280 more than XV! I can get kind of stubborn (must be that German blood in me) and as far as I'm concerned the prices Mopar Performance is trying to get is gouging, plain and simple. I know darn good their markup is WAY over what it's costing them to make those manifolds. There's a guy over on the Hot Heads Research board who is getting ready to cast some 4 bbl intakes for the early DeSoto hemi and he's saying they are not going to be cheap (around $500 each) because it's a small run. Now, you take an outfit like Mopar Performance who is selling these manifolds AND putting them on every 5.7 crate motor that's going out the door and that amounts to a LOT more manifolds than the other guy who's making manifolds for a niche market (a 50 year old hemi). Something's not right here and I'm not buying in to it! Heck, Edelbrock is only pricing their dual four manifold at $399!
