intersting - just reading it again - section 4 I posted says it was a aluminum intake manifold - we all hear that early 70's got some, but not 71's. My car has an aluminum - I was just under the impression that it was replaced previous to my ownership (1994) - maybe a mistake by the mag ? Does your friend have an alum. intake ? I'm still trying to find out my car's history - sold from dealer 30 miles east of my house - found @30 miles west of my house - still no luck - NYSDMV is not the most cooperative organization in the world - oh well...
