I gotcha, Kieth.
I probably came across as a bit spoiled in the last post. I should have thought a little more beforehand.
I have a 440 distributor from Mopar Performance as part of their electronic conversion kit. I bought it in 2001. It has been recurved once by a guy that ran a shop with a dyno. He set the initial to 17 degrees and had to limit total mechanical advance to 31 degrees to avoid the dreaded detonation. I have since tried other settings, but this is where the car ran best with 91 octane gas. I'm running 10.8 compression with Edelbrock aluminum heads and a MP '509 cam. I have planned to swap back to a Comp cam again. I liked the street manners of the 285 XE stick when I ran it.
