'65 chevy c10 - bad vibrations! things to check?

[NF65Fleetside]

I got down and dirty with my truck this morning and actually the fellas that did my swap changed out all the driveshaft parts for new hardware...so then I had my friend whos pretty nifty with motors check things out and yes we came to the conclusion it was timing....Ill get it adjusted either tomorrow or over the weekend, I dont have a gun of my own so have to wait til I get time to head over to the local garage. thanks for the info guys and great job Woogeroo
