Horsehockey! My quickest ETs have always come with an EGT in the range of 1460F on #6. That's for a 306 N/A combination. Point being, that you can't believe anything anyone tells you about the 'right' EGT temperature. Its a tuning tool, and its purely qualitative, not quantitative. There are any number of parameters that affect the actual temperature measurement, some of them being: axial location on header, depth of placement in flow stream, shape/swirl of exhaust port, cam overlap, etc. So all you can do is install the probe, and start a log of EGT versus setup and keep track of how things such as jets, fuel pressure, shift points, etc. affect the EGT. Then use these trends to refine your combination and tune for weather, etc. Believe it or not, but I can see as much as 20-degrees change in EGT just by changing from Sunoco 110 to VP C12.
