I agree 100%.No need for anything other than internal balancing.Contact me if you need help with selection or any info.

I plan on having a 400 stroker motor built soon so I was taking a look at stroker kits and see that they are available in internal, external and non-balanced configurations. Could someone please provide some information on this subject? Is the type of balancing a matter of personal preference or does the type of motor you are building dictate how it needs to be balanced?
A internal balanced crankshaft assembly, motor, needs no special externall balanced torque converter, flywheel or crankshaft balancer. A exteranl balanced motor has to have the correct and matching flywheel, flexplate, or in Mopars case, the correct external balanced torque converter. A non balanced stroker crankshaft assembly will need to be balanced with the correct components like the balancer, flexplate, flywheel or torque converter. Internally balanced components like the balancers, flywheels or in Mopars case the torque converters, are already nuetral balanced from the manufatuers so they can be bolted on any internally balance motors there designe to fit like BB Mopar V8 ,Hemi or SB and so on  BTW, I always have all the rotating parts sent to the balancer so they can be check and correct any parts that are not perfect or if they need it  You can't be to careful on any parts  IHTHS

External balance is less effective at controling vibration and puts more stress on the crank and bearings because the weight ends up very far from the source of the out of balance (the crank throw, rods, pistons, rings...). Avoid external balance if possible in high RPM engines but in stock engines it is no big deal, the crossover point is generally a heated debate

Contact Bob at Racing Research in Clinton Township, Michigan. he has over 30 years in the machine shop business and is top notch. He can explain balancing so you can understand it. Lots of bad info out there. But yes, internally balancing is the best way to go for simplicity, and in case you fail a convertor or damper, you can simply replace them with a neutrally balanced part. Bob can be reached at 586-949-3790. They build engines and transmissions there too, Mopar specialists.
Engine dynos are almost up and running. A Superflow for 1000 HP and another that is capable pf 3000 hp for you balls to the wall racers.

 This explains it very correctly . need no more info . Internal balancing all the way . stroke that 400 up to a 500ci . I have a brand new internally balanced putting together now .
