best street/strip 12 bolt diff - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey everybody! I'm thinking about finally ditching the open differential in my truck. I was just curious if anybody had any suggestions for a differential for a street/strip truck. I've been looking at the Detroit TrueTrac, but wasn't sure how well they "lock up" during a launch. Also been looking at Detroit Lockers and Auburn Limited Slips as well. I have the factory truck 12 bolt, TH400, 355sbc with guesstimated 425hp at the flywheel and I'll be going to either a 4.11 or 3.73 rear gear. Thanks in advance.
