After installing a new pro street stroker 383/496 in my 69 Roadrunner......I'm getting some not so sweet vibrations above 70 mph. At 120 the vibration is so bad, forget about looking out the rear view mirror.....and there's a lot more left in this motor. Looking for some ideas on where to start diagnosing the problem. I have an original A833 4-speed transmission, original driveshaft, 3:23 gears in a 486 posi rearend.
