Is the stock 1968 340 converter neutral balance. My 408 stroker motor calls for a "weighted 360 pre magnum flex plate" I'm using a b&m 10236 flex plate and a stock 340 converter. I have a small vibration that's bugging me. eliminating suspects
b&m 10236 flex plate
Chrysler '71-'92 externally balanced 360 with A-727 (These special Chrysler Flexplates must be used when changing converters on an externally balanced engine.) Is this considered a weighted flex plate? Thanks 
the stock 340 converter should be a neutral balanced converter..no weights...the weights are pretty obvious if you look at the converter...
yes..that flexplate is for an externally balanced 360 and should have been used went the engine was balanced...
how about the drive shaft??? pinion angle???
