Hi folks,
I have a question regarding exhaust headers.
I finally got my beast somewhat dialed in. Basically, it's FTI's Pure Street combo with AFR 165's with all the upgraded goodies, ported Performer RPM, custom cam, Scorpion RR's, lightweight pushrods, Aeromotive fuel system, 30# injectors, etc.
I am using my old FMS ceramic-coated headers, Bassani X-pipe, and MAC Pro-Dumps.
Well, after getting the thing fired up, and letting it warm up for 10 min. or so, I am noticing my headers glowing orange. My Autometer fuel/air ratio meter was reading lean at 36psi of fuel pressure, so I bumped it up to 40. I had to adjust the idle to around 900 RPM to keep it from surging.
Maybe since this is an upgrade from an essentially stock engine, I am not used to seeing glowing headers. However, it seems to me that these headers got a little too hot a little too quickly. The engine was just at idle 99% of the time during this period.
Any input appreciated.
