Are you running the same spring perch width as a stock mini-truck front axle? In other words, did you modify the front spring hanger and run the goofy shackles to go to a wider spring perch location?
Sorry to hear that about your motor. That is so frustrating 
I am running a wider 31" spring hanger, that is why I moved the shackles.
I have been looking into the 3.4 swap and it should be pretty easy with everything that I have.
Going to see what is up for sure with my engine on Friday.
