Spark Timing

[Billy Nees]

Chris, excellent subject but, I think that it is a subject that becomes too "singular" in scope. If we can agree that, after a certain point, timing becomes a "crutch" then you will know what I am meaning by it being too "singular".
Most of the "stuff" that I'm playing with right now seems to naturally want about 33 or 34 degrees total. That being said, this past year, I took one of my motors and installed it in a car weighing almost 400 lbs. more than what it is usually in and the same motor/trans/converter (more gear) wanted 6 degrees more timing to "peak" its ET. I think that you're truck is a good example of that because (IMHO) I don't believe that you're motor (using C-11 especially) should need 40 degrees of timing. Please reply as this is a subject that really does interest me.
