First Generation Firebird-L Mailing List ......................................................................... Steve Stick with the original 69 shroud. Make sure you have the lower air baffles in place. Switch the fan to a clutch-fan... for 2 reasons... number one, the fixed fan is robbing 8-10 horsepower, number two, that humming noise while driving down the highway will cease! LOL Do you have the x-panels in place in front of the radiator? Having all those fans, the 2 in front, one behind, and the engine fan, is actually counter-productive because if they aren't all running at the same time, one (or more), is blocking air movement. Just my opinion, but I bet if you take off at least the inside mounted fan, you will see a noticeable difference. Also, the thermostat should be a 195* or less.

I've been running the 1969 radiator shroud with the 1977 400 engine that came in the 1969 Firebird that I bought. It originally had the 1969 350 engine in it. I'm concerned with the fan not being in the proper position relative to the shroud when using only stock parts. I've played with fan spacers and with modifying the 1969 shroud but I'm sure someone out there has a mid 70s engine in 1969 Firebird and may be able to tell me which year shroud (1969 or 1977?) that they are using which works well with stock parts relative to positioning with the fan. I'm also not sure if the modified engine mount position is exactly correct, but I'm willing to try a shroud that someone else says has worked out for them, then modify engine position as needed with proper engine mount templates. I would like the shroud / fan situation to look stock even though it's not.

I'd be driving my creation I call the 'What-If Hurst Edition' 1969 Firebird Trans Am round trip Florida / Colorado. ------------------------------------------------------------------------ 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/>
