I'd sell the Victor Jr. and get the Edelbrock 7501 new or used preferably on ebay and look for one with a garantee so if its screwed just send it back.
Never buy anything no returns accpeted or a seller with negative feedback.
However you want the best of both worlds get The Mcfarland Torque link or HiTech Torque link the same thing. Ebay is the best place to get it.
Its funny shapped and its very tall. It offers great mid range torque and great HP in the highend. You have the ingrediants to make that intake come to life with your rear 410's Your carb is fine. You get burnout quality of a dual plane and the highend a single plane screamer.
Google it its a design like no other. And people will be impressed because its a design few see everyday.[/img]
