the intakes look real good, but if i were atempting to get 600 horses into a vega, i would go with an already proven set up. i would use a company that matches thier intakes to trier heads, like a brodix intake with a set of brodix heads. or dart on dart, edelbrock on edelbrock. these companies designed thier heads and intakes as a unit. sure they are probably very close to one another, but when you are buying power you might as well buy what was mated together as a unit.
