I am not driving it this way, I have not even driven out of the driveway yet, but figured I would post an update. I was concerned a little about the ramjet cam as a few people said I may have trouble getting it to idle with the 109 lc. At least with the 1995 computer it idles fine even with the stock timing and fuel. I have done some very conservative changes to the chip now, but the fuel tables need to be dialed in better before loading it too much or driving. I ordered a mr gasket 180 high flow thermostat (Robert Shaw Copy) thinking it may be better for towing. I think that will have to be changed out before the van leaves the driveway. Too much trouble keeping it up the temperature in winter weather. As soon as it starts to open the temp drops by 20 degrees fast, so the temp gauge pogos back and forth every 10 minutes or so. It had a super-stat in it before, and it did fine in all weather. Live and learn.
