1970 L-78 Camaro

[CamarosRus]

Mr.70,I believe that all 1970 L-78 Camaros came with the CO Dual Snorkel Air Cleaner(see attached picture).....This air cleaner was also used on "some" 1970 L-78 Novas and Non-cowl L-78 and LS-6 Chevelles. Chuck Hansen (ACES) has suggested that getting away from the Open Element A.C. had to do with new 1970 laws regarding noise. I would love to have some official G.M. answer but dont know how to research this. I have been looking at the 70 L-78 Camaros now for many years and while many of them are missing the original air cleaner, I do feel the dual snorkel was used exclusively. The swap meet prices on these is very high and heard from the sellers mouth that last year a NOS one sold for $2400. I have three Van Nuys Plant 70 L-78 build sheet copies. Norwood 70 Camaros did not come with build sheets. 1) #511596 Mulsanne Blue had CO air cleaner(Dual Snorkel) and 052 Tach(may I assume 6500/7000)listed as U14 IP Gauges on option list. This was a project I once bought without correct block or trans, and went back to the seller in St Louis. 2) #505462 incomplete partial build sheet. CO air cleaner and -- Tach/Gauge delete. 3)#521043 Cortez Silver with CO air cleaner and again -- Tach/Gauge delete. All three cars had M-21 4 spd CLS Ratio.
