First Generation Firebird-L Mailing List ......................................................................... 62's were the standard performance 400 head for 69 48's, which are the same head as the 62, were used for the ram-air "3" option.
If you got air conditioning in your 69 with the ram air 3 option, you got 62's... >From 68 to 70 all D ports with large valves are the same head. the numbers are what tell the factory/ dealer / mechanic what motor they are supposedly to be working on.

Just a 2 letter stamping. ------------------------------------------------------------------------ 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/>
