Well, the good news is I got the rack installed, toe in set, and she goes down the road straight. The bad news is I'm running on 7-cyclinders. I was idling along and all of a sudden she started missing. Limped home and isolated it to #6 being the culprit. It's too hot to do anything with right now, so after she cools down I'll check the plug and wire. No noise so I don't think it is a valve..... just have to wait and see. Damn it!!!
