Hi I need some help.

I have a 429 CJ or what I think is one that I am looking at selling. It was rebuilt about 14000 miles ago and runs like a top. Some people are questioning if it a true CJ besides what the air cleaner has to say. Here are the casting numbers.

Block DOVE A
Heads DOVE C
Intake DOVE 9425 B

Pistons are Flat tops with double eye brows is what one guy said.

Can any one help????

John
