Cant get rid of vibe after 350 block instal

Tried shiming my carrier bearing from 1/4 inch all the way to 1 inch after puting the 350 rear blocks on my 250. Now I get some vibration on a semi hard take off. Vibration was not there before. u joints are all fine. Im wondering how much shiming most guys have done to get rid of this vibration. I thought 1/4 inch per inch of height would do it, but that did not work for me. Any Ideas are greatly appricated.

Yes, I had flat blocks and stayed with flat blocks. I wonder If I should try no shim at all?

By no shim at all I mean no carrier bearing shim, I have no shims in my flat blocks.

That is what i was thinking, that would be 2 to 3 inches worth of shims. Do you sell one big thick shim?

I don't understand why a 3" level kit would even have a problem with adding a F350 rear block..did you take off the DS? Many early SD's TC flanger were out of round..and only work well in one spot.

Trevor at PMF has whats needed if in fact this is your problem ...Adjustable Center Carrier Bearing Drop Bracket - Precision Metal Fab

What is a DS and a TC? on another note I got the vibe fixed, I had to drop the carrier bearing 1 inch on the front side and 1 1/4 inch on the back side so it is angled with the drive line. Thanks for the help. I figured it out when I finally looked under my friends f350 and saw his bearing came stock with some angle in it. wish I had compared the two a month ago. thanks for your help will be in touch soon to get shocks.
