I've got this small block 350 just swapped it in my 91YJ it's crazy fast . Problem is I'm getting a bad vibration at 25-30mph then it dies off a little but is still noticeable
When I coast it goes away
I want to blame my rear driveshaft angle but any ideas ??

If it does not have a SYE, then it look off to me. A pic from the side would be better, or just check the angles yourself, without a SYE, I think you should be 2degs. low at the pinyon end.

its hard to see in the picture but it looks like you do not have a double cardan shaft.
And if not your t-case and rear axle yolks should be parallel.
