    Most of the reason GM didn't put air on them is because the lifters were supposed to be adjusted every year and a/c compressor made that too difficult to do without discharging the system.

    Another reason for no A/C on the Z28 was that it slowed down the car. Z28s in those days were not supposed to be slow.
    If you wanted slow, you bought a 307 Sport Coupe with A/C.

    I live in South Carolina / Georgia. Wow it's hot with no A/C in my 70 Z28, even late afternoon. Do you put it up in summer or add Vintage Air. I am a left leg above the knee Amputee and heat is tough. Not complaining, I love my Z28 period correct as she sits. What are your thoughts? Any Amputees on this blog?? Dw

    I have added A/C to my 70 Z28. Tired of sweating my ass off. My Camaro is not for sale so I will enjoy the cool air...

    The 72 LT1 air cars used 3.55 M20 combos - with a BB tach utilizing a 5600 redline - (engine was EXACTLY the same) to save the compressor and keep from throwing belts... the 73 Z28 with AC used a 5600 REDLINE tach as well with the non ac Z28 using a 6000 redline tach.

    So you're saying the tachs for a 73Z with AC and a 73Z non-AC had different redlines? Pictures?
