has anybody used the edelbrock repro intake on a 455? I have a 1970 stage1 455 from a GS. an have everything but the intake. I know the factory cast intake in super heavy. Planing on building it fairly mild so it will be streetable. they built good power stock so thinking mild cam headers an aluminum intake. can't aford the edelbrock aluminum heads.(there outrageously expensive) sure they would flow great but the stock heads with alittle work will suit my purpose just fine. any help would be apreciated! an does anybody know a good but decent priced header?
