"Mystery" Chevelle LS-6 in NEW Muscle Car Review???

[Mr70]

The CO code is the suffix listed on the buildsheet for the Dual Snorkel Air cleaner.Also found on the side of the Dual housing is a decal that states"Keep your GM car all GM".All GM air cleaners have this decal.The Dual has the CO suffix on it also.
While at Peotone Il. swap last June,there was a Dual Snorkel for sale.It had the Snorkels completely cut off,but had the chrome lid and CO decal still intact for $25.00.Those orignal decals are hard to find in good shape...
