Tuning with jets, Power valves and an O2 guage

Time for tuning!
Now that I have the car up and running, I'm trying to tune it. I installed an AEM wideband guage and have a bunch of jets, power valves and accelerator pump cams.


Here is a recap. 440 based 493 with Edelbrock heads, RPM intake, 2" TTI headers and 10.7 compression. Lunati solid lifter cam with 261*/271* @ .050 556./.578 lift INT/EXH. MP electronic ignition with chrome ECU New wires and plugs. Barry Grant Speed Demon 850 VS carb w/o choke. 85/93 jets stock with 6.5 Power Valve.

I broke in the cam last week. The engine ran hot during the first 15 minutes of run time, so I shut down and let it cool. The same thing happened on the second run. Fuel was boiling in the line which was partlt due to having no fan shroud along with the engine running lean. I have since fabbed up a fan shroud.

Today I installed an AEM brand wideband Air/Fuel guage. It has an oxygen sensor mounted in the RH header, 6" forward of the collector flange. I mounted the guage in a panel I put in place of the ashtray.
