A 406 is merely a 400- bored .030" oversize. ........no "stroker" to it...... Check your harmonic dampener or flexplate to make sure you have "400" externall-balanced pieces in there. If you have a "350" internal-balance flexplate or dampener it's gonna have a cranktrain vibration...... and eventually you'll have a busted crankshaft.
