It's a 1970 motor assembled Dec 22, 1969 with a factory rating of 350 horse power, probably out of a C body. I think the only difference are the cam, valve size and carbureation. It would have an HP stamped on the top engine pad if it came in a muscle car, What are the casting numbers on the heads?
