While lately I have been concerning myself with the possibility of a camshaft and converter change, I'm still curious about the way this car runs so rich at cruise rpm.
Nothing has changed since the last few posts in this thread, but today I did order a Quick Fuel metering block kit with replaceable bleeds. It seems that since the car runs strong at WOT with the #83 jets but the guage reads rich at cruise with them, I'm going to try using smaller main jets and larger orifices in the PVCR. It was suggested to try using a lower rated PV to get a head start against a WOT lean-out condition (or stumble). I'll certainly try that too.
I also ressurected this thread in direct response to a thread in the General forum about members that do NOT post results after asking for help.
