Re: Smog
Is there any chance that the '67 410 hp engines were based on the 390hp 427?

Re: Smog
Several car magazines tested Hi-perf bb/auto cars in 1969. Hot Rod did an L78 Nova, PHR a L89 Camaro (last seen on ebay), Super Stock the #5 ZL1. All these had AIR.
PHR also did a L34/auto Nova, no AIR.

Re: Smog
The 68 Gibb automatic COPO Nova's came with the smog pump. If you happen to have the Nov. 1968 issue of PHR, there is a picture of one in the article about the 396-427 Nova's Harrell prepared.

Re: Smog
William: Not really familiar with all those articles. What month of Super Stock magazine is that? The only one I know of is May 69...that car had headers installed, so no smog on it at the time. That article had great engine bay photo's. Really showed the paint change colour on the firewall well!

Re: Smog
I have not seen any original pictures of a 1969 or 70 L78 or L72 that did not have the A.I.R. system on it. Some lower HP 396 engines did not have A.I.R. and some lower HP engines got the TCS system instead of A.I.R. I would think that the carb and distributor part numbers would be different for a car with or without A.I.R. The slightest engine calibration change required a different part number for carb and distributor. For example some cars with same engine but with auto or manual trans has different part no. carb and distributor. Also the fan belt will be different part number for A.I.R. or non A.I.R. and I cannot find part numbers for a 69 L78 or L72 without A.I.R. There is usually a paper trail in the part numbers.
