1965 chevy high performance engine codes

[black69]

I got a hold of owner #2 of the car on saturday who sold this car for $2500. he said its original motor was a high horse power engine and the original owner in detroit kept it, and stuck in the 300hp. he said he will visit the original owner of the car as he still knows where he got the car from. If no one is home we will get the address and give it to us. He believes he put it in a race car or was saving it for a race car. I wish you could tell what a malibu car was from the trans stamp or rear end code (like on L78 vettes).
