Does it have all the vacumm plumbing to the temp switch at the front of the manifold? If so, perhaps that vacumm switch has gone bad and you are getting advaance when it's cold but it's retarding at normal temp and the lower speed is killing the engine.

Hello all, I am working on a ' 67 firebird with a 10:1 400 motor, #62 heads, a ..465" cam, HEI dist., stock quad style intake, 350 auto, and a Holley 4412 2 barrel carb. This combo was in a asphalt street stock race car once and has been in this weekend driven street car since. It ran great until about 6 months ago. The problem is at hot idle. It starts and runs good cold. Once it is up to operating temp (195ish) it will die in gear at idle. It will start right up and idle at a faster than normal rate in neutral, but die in gear. Once it is cold it is fine again. I have rebuilt the carb with no improvement. Replaced the main metering block with no improvement. I have searched for vacuum leaks but have found none. I don't know if I have included enough info, but I am at a loss. Any ideas? I was thinking about doing a rebuild on the distributor, just to scratch it off the list. Thanks in advance. ------------------------------------------------------------------------ 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/> Donations: <http://FirstGenFirebird.org/store/cart.mv?999999> FGF Merchandise: <http://FirstGenFirebird.org/store> ------------------------------------------------------------------------ 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/> Donations: <http://FirstGenFirebird.org/store/cart.mv?999999> FGF Merchandise: <http://FirstGenFirebird.org/store>
