Help with Possible 69 Camaro COPO engine

[1dw]

I had a friend with a 69 daytona yellow in pa, he blew the 427 up and replaced it with a 396. he later traded it in,also in pa.someone bought it from the dealer and I saw the car for a short while, then it left the area. sounds like the one. I have more info on the car, and who owned it and the history behind it if it's the one. I hope it is. dwyellow. I only joined supercar reigistry because we always wondered what happened to this car. the years you are talkng about all seem correct.
