William, are you saying some of the 69 Yenkos were rated at 450HP from the factory?

Re: 1969 (COPO?) Camaro Information Search!
 

Nope. But he obviously knew they were rated @450hp at one time and felt justified in using the number in his marketing info.

Those were the old gross HP days anyways. Add the "as-installed" equipment [fan, alternator, etc.] and you have net hp, the real number. I recall maybe 10 years ago one of the mags did a feature on a L72 clone build-up and it just made the 425 number. Maybe the 450 was never real.

I'm aware that with today's rings and oil [and maybe cement pumped through the ports] an L72 can do better.

Ok folks. Been a while. He found a couple pics. Notice the one where there appears to be id3ntical cars. His buddy bought the same color camaro with a 305? And dress3d it up to look exactly like my uncles. He would drive around and set up races then retu4n for the bad boy. He says no one ever suspected a thing!

I had a 307 LeMans blue 69 (my 1st 69) in 1973 ... vette rallys though, had the white pin stripes too (no shackles, we called the shackles hillbilly hi-jackers ... [img]<<GRAEMLIN_URL>>/smile.gif[/img] ) ... cool pics

He also mentioned that he removed the valve covers one time and &quot;super high performance&quot; was stamped on the heads. Does that mean anything to you guys?

Re: 1969 (COPO?) Camaro Information Search!
 

Sounds like an L72 copo with HI PERF cast in the iron heads, no such thing on the alum. heads. The $4700 sticker price range is correct for a iron block copo.

I see bait and switch street racing writen all over those 2 cars. [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

Re: 1969 (COPO?) Camaro Information Search!
 

Thanks neresto, but still a pretty rare car right?

Re: 1969 (COPO?) Camaro Information Search!
 

You were a lucky individual to have the privilege to drive/own any 427 Camaro or Chevelle in 1969 as well as in 2012! Judging by the photo it was certainly an original copo and not converted to a 427 car.

Anyone notice an X11 to boot? What color interior did it have? Was it deluxe?
