You have a serious machine. yes, & get a 318 (neutral) dampener. plus on the other end this will let you get/use a good aftermarket neutral converter & swap em later if ever needed.

Being a cast crank and the other things that would need to be changed.. damper and conv and the balancing cost... I dont think I would.. but if your buying a balancer and you can knock the weight off of the conv it would be up to you.. on all my forged and billet cranks I always go internal but I also turn way more rpm than you

Last time I had this done it cost a little over 500 bucks. Probably not worth it. The other stock crank 360 apps I've messed with, just used the b&m plate, and external balancer with the neutral converter. Just to clarify the external still got sent out for balance job. Which was around 200 bucks.

SRP pistons (at least flat-tops)and Scat I-beam rods are lighter than stock. You may not need as much Mallory metal, if any, as you may think using a neutral damper/balancer and flexplate!

I dont think this combination of rods/pistons will require any mallory metal.
BTW, using King rod bearings will knock quite a few grams off.
