I wasn't calling you out or anything, just adding some info for those that probably didn't know the /6 was used in full size dodge trucks. :D (and the old flathead 6's before that... the flathead 218 in my '48 only puts out like 95hp)
super low compression and heavy internals, the perfect candidate for a centrifugal supercharger. I've even seen vintage (1940's / 50's) superchargers on ebay from time to time for those engines.
