Vibration over 65mph

Just got in a whole bunch of parts for the car. Trickflow 190 heads for hydraulic roller, Edelbrock air gap, and all gaskets and seals.

I ordered a hydraulic roller camshaft kit from Hughes (lifters, cam, timing set, cam keys, etc) and apparently the cam and timing set was on back order. Don’t know how long it’s going to take to arrive but I hope it’s soon.

Never had any experience with hughes before but I’ve read that their customer service isn’t the best. I gave them a call and the guy on the phone didn’t seem too bad.
