Header temps
Is there a good temperature for headers?
SBC 355, pump gas, 671 blower.
I run about 675*F 2 inches out of the aluminum head at idle.
Is this high? My underhood temps seem hot.
Is the temp something I can use to tune idle timing and mixture?
Plugs look good after a WOT pass.
I have new XFI fuel injection and more adjustability that I am used to.
