First Generation Firebird-L Mailing List ......................................................................... Doesn't the 74 has a much lower compression ratio? My thinking is that with the higher ratio's in the pre-emissions engines you might need to keep the gap smaller.

FYI, the spec for my 74 HEI 400 pontiac is .060.

YEs, the higher spark voltage from the HEI allows you to use a larger gap. I think around .040 would work. ------------------------------------------------------------------------ Submissions to Firebird-L: <[email protected]> Unsubscribe from Firebird-L: <[email protected]> Help: <http://FirstGenFirebird.org/firebird/Firebird-L.html> Classifieds: <http://FirstGenFirebird.org/ubb/> Owner Pictures: <http://FirstGenFirebird.org/show/> ------------------------------------------------------------------------ Submissions to Firebird-L: <[email protected]> Unsubscribe from Firebird-L: <[email protected]> Help: <http://FirstGenFirebird.org/firebird/Firebird-L.html> Classifieds: <http://FirstGenFirebird.org/ubb/> Owner Pictures: <http://FirstGenFirebird.org/show/>
