No they don't glow, the cam I have (Erson 453 lift) was matched to the build of the engine by a local speed shop and Erson said to set the timing 4 degrees +. I have a timing tab that gives a 4 degrees advanced tab, at 1000 rpm I show dead 4+ with a timing light. Am I missing something with this?
If Erson said set timing at 4* they probably meant to install at 4* advance, not the running timing on the harmonic balancer. i've never seen a cam company tell you what to set the engine timing to. I would get or borrow a timing light with the ajustable timing control, and bring the rpm's up to about 3,000 rpms and set the timing to 36/38 degrees total timing.
As Todd says total timing not idle timing.

Thanks for the great info. I will try this and see what happens, I know a couple of other racers that run late models and set very similar, didn't think about it until you mentioned it.
