Yes, to some degree but the perplexity of getting one checked out to be what they say it is and spend a bunch of money and it isn't what they say it is. I called a dealer on one that had one that I liked and ask, him how did he know it was a True SS answer because the original ower said it was. I said, you will have to show me proof he said, he couldn't. On a 69 I would need a build sheet or protecto plate and compare them with the car. I hear they are forging build sheets and restamping blocks and passing them off. Very leary of buying something forged for this kind of money
