Ford didn't balance every engine to ONE specific flywheel like you do when you have a motor balanced. If they did any time you replaced a flexplate or flywheel you would have to tear your motor down and have it balanced. His motor will be just fine. I changed flywheels on my pulling truck last season and called the guy that balanced it to see if anything needed checked. He told me that it would be OK, and it ran all season turning around 7,000 and the bearings still looked new when I took it apart last fall.

i have talked to reputable engine builders along with many experienced people on this forum like greenhighboy who have done this before along with people around here that have done this same thing and have seen it myself...the 360 flywheel will work just fine with the internally balanced 460...the externally balanced 460 is a different story.

Yea, believe it or not this is SOP when bolting up an np-435 or t-18 to a 460, no big deal. I have never gotten satisfactory info on how the make the starter work well consistantly. Typically, guys use the starter for the 460, or 400 but some guys report they were able to just bolt it right up, others say they had to shim them. I know thats not much help, but search for the thread on the np-435 swap in the 73-79 forum, this was covered recently.
