Hello from BluePrint Engines!

I also have a question, why does the website say it takes a mag style balancer, when most 4" cranks are neutral balanced?
The website is correct, as noted below.
Harmonic Balancer: 360 EXTERNALLY BALANCED '93-'97, 7.25" Diameter
Flexplate/Flywheel: Pre-Magnum, Weighed 360
