Scott/Jack,

As noted, I have the 8578. It does not have a vacuum advance, and I did not notice any difference in drivability from when it had the stock Duraspark stuff in it. The 8578 was recommended by Mark Dove of SPF in Ohio, as what they use on the stroker motors they build.

Also recommended was about 36-38 degrees total timing.

Brad
