OK cool, so, IF I don’t have a flexplate, I use a B&M 360 flexplate designer for neutral balance converters.
Correct? And a front harmonic balancer like yours or one for the listed years on the Blue Print site.
Both of our current 408 engines need the magnum weighted damper. thats as of today. the 4085 and 4082 based PN's
For the flexplate 95% of the time, you order one for a LA360 balanced engine. BECAUSE most aftermarket torque converter are neutral. so the imbalance is made up at the flexplate.
Chrysler in their infinite wisdom from the factory, used NON weighted flexplates, and put the weight on the converter. not many aftermarket companies weight the converter. but i have seen it.
so the only reason to buy a neutral flexplate for our 408, is if your converter was built with the weight on it. which is rare....or stock....and stock doesn't jive well with a cam anyways.
