According to my book, they came off a 69-79 truck, 350 cu in. As far as the year, under the valve cover is another casting # Should be a letter for month, ( A=jan, B=feb etc.) next numbers, day of month, last digit is year. If the last digit is a 9, you will have to determine if it is 69 or 79. Hope this helps.
