Re: "Mystery" Chevelle LS-6 in NEW Muscle Car Review???
Pete's ZL-1 seems to do very well through the stock, untouched manifolds! I would call low 12s on Polyglass and through manifolds doing "pretty damn well"[img]/ubbthreads/images/icons/grin.gif[/img]! Heck, his yellow COPO Chevelle ran 12.80s(?) with the stock manifolds and working smog setup!
You guys should make a pilgrimage to the Pure Stock Drags sometime...these cars actually WILL run through the stock exhaust setup...
