If I was buying a 70's big car and had the budget, I would be bidding on this real P Code 429 police car-

Cool car!! 72 was kinda a off year for the 429 though.. up to 71 had great heads, and high compression.. granted with the fuel needs to go along with it... For 73 they improved the heads so they worked better on the lower compression motors. I have sitting in a 71 parts car a 429 2bbl motor.. for some reason they offered a 2bbl on a 10 3/4 : 1 engine!! One day it will end up in my 72 convertible.
