We drove it to town and back. It runs better, liking the more initial. That said, Kitty says the rattle is about the same and I think I know why. It's the heat. I cannot MAKE it rattle ONE IOTA until it gets some temp on the gauge. When cold, now with more initial, it pops off almost without hittin the key. I mean it's READY. But when we went into the post office and it sat there heat soaking, it still had long crank time with the throttle open a hair....and the temp gauge was almost at 3/4. As soon as it busts off it starts cooling right down. I think the high flow thermostat is going to help a good bit. It did on my truck. It was running in the half way range and when I put in a high flow thermostat now it barely comes off the cold line.....and it's right. I've checked it with the heat gun. I'll get on top of it. I may file out the zero holes on the limiter plate and get them to 6 degrees and see what's goin on then. Obviously, for "whatever" reason, the slots are different for this distributor. Whether it's because it's a slant six distributor and maybe a little different, I don't know. I still have several tuning options left, so we'll get it. I'm pretty confident. If nothing else, now I have some room to retard the initial and that will get it out for sure. But I believe the cooler, high flow thermostat will pretty much solve it. I am going to try that first and report back.
