Howdy folks! Just wondering if someone has any info/experience with the 8981 timing computer. My questions are this: Does that work with a 6AL box or right off the distributor? Also, must one lock out the mechanical advance in the dist to use one of these? And, what about the vacuum advance? Thanx much!
