Great info guys, thank you!

74's are at least 300 lbs. heavier.

Love learning all the little details that make the 73 Z28 so unique. Another reason this is the best car site ever, thanks guys!

That's my old car. In the family since new. Sold in 1999 with 21,000 original miles.

It is amazing that a 21000 mile car is missing the valve cover wire clips?

My dad liked a clean looking engine. After my Brother was killed in 1974 he stripped the clips off the engine along with the smog and placed all of what he called "junk" in a box stashed in the barn loft in 1975.

In 1980 when I got the car- he took the box down from the attic and tossed the original parts he stripped off the car in the trash. He told me later he was afraid that I was going to put "that junk" back on.

He was right. I would have.

Great background info on the car. Junk, that is why finding parts is hard and expensive because your Dad was not alone in his thinking. Thanks for the info.

Great info and clarity on the second gens and the Type LT. I'd love to find a nice LT RS Z

Plastic technology on cars was still relatively new in 1974 and the previous generation did not trust it.

SMOG: was a "power robber" so it typically came off first.

Just a few years earlier Opticlean was under the hood from the factory in a glass bottle... so there you go the pace of technology change.

I still recall My brother saying "look I got the little Bastard" As he held the seat belt buzzer speaker in his hand. I asked him for it and kept it.

The buzzer was in the console box when I sold the car.
