Try to paint this picture as best I can.Been running an old Mcandless 360 w/a 727 behind it for years and all has been fine,until now.I just swapped in a t-5 manual trans and used a zero bal. flywheel and when I started it the engine had a terrible imbalance vibration.I then realized I had been running a b&m flex plate w/ the cut out which im assuming is for an externally bal. setup.I then took the flywheel to my local engine guy and had him balance the flywheel to a 360 spec.Vibration was much less severe ,but still there.I dont know what to do now.Should I just get a 360 flywheel and try it?Maybe he didnt bal. it correctly.Any and all suggestions would be appreciated.

Just a guess but sounds like the proper flywheel is in order

When my flywheel was balanced the pp also had to be boltd up at the same time.

Hope you get it figured out.

If you would like for me to call you PM me your number and I will be glad to call you. I have had this happen many times with customers and I have an easy solution.

Proper balancing,

I purchased this used flywheel described as a 360 externally balanced piece,but when I bolted it up to my 360 it vibrated like crazy.It felt the same as the zero balanced flywheel I had mistakenly installed previously.From what I understand the 360 wheels usually have three very large balance holes on the back side about half way out from the center.Any pics or info is appreciated.

Justin,

I know very little about this balancing thing, internal.. external... I'm always asking for help..

But I do have an external balanced flywheel sitting around doing nothing, so if you need to use it or try it, just let me know..
