Locker or sure grip for 8.75? What are you running in your hot street/strip car?

An 8 3/4 built right is plenty for what your putting throught it,i have one with Moser axles and 4.30's with a spool and billet yokes,i previously had a 489 3.91's and trac-loc,handles everything my stroker or 360 can throw at it,wheels up off the line..:-D:-D
