First Generation Firebird-L Mailing List ......................................................................... Steve,
I run a 74 400 in my 69. You should always run the shroud from the original car, not the donor. The original shroud is setup for the original radiator and brackets, etc. All 400 engine dimensions are identical. The only thing that might change is the water pump (69's have two water pumps, one shorter and one longer) and the fan clutch (some might be shorter, longer, etc). I would look up the part numbers at an auto parts house between a fan clutch on the 77 that you got, and the 69. Make sure they are the same. Do the same with the water pump. Worst case scenario, you might need to get a new pump/clutch that pushes the fan into the shroud more to increase efficiency. Also, make sure you use the 69 fan blades, not the 77.

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/>
