I have had my 85 for three years now, rebuilt engine, trans, new paint and have never been happy with it. Never really ran right. I don't have a way to properly tune the cam sensor so I been making adjsutments and driving keeping track of previos adjsutments. It looks like I hit the sweet spot. enjoyed cruising this car so much today, feels like it's making the power it's supposed to. Gets good scratch off the line, damm good scratch into second, if it ain't straight it could turn around on you and pulls hard top end. No more surging, hanging up shift points and lag is cut in half. Stoked.
