Re: cracked exhaust manifold on 232

[Matt Haas <mhaas@xxxxxxx>]

Jay,

You usually set the curb idle speed on a car with an automatic while it's 
in drive. Did you have the intake manifold checked to make sure it's flat? 
Did you follow the torque sequence from the TSB information I posted 
(http://www.mattsoldcars.com/RestoreAmerican/loose_intake.shtml)? Also, I 
have a much better idle now with just the intake gasket than I did with 
using the combination gasket. Finally, did you try adjusting the fuel 
mixture? A lean or very rich mixture can cause the engine to run rough.
