New Coan Converter

Watching as well. I gotta wonder why we are all not actively trading (buying selling trading etc) our converters here. I rarely see one for sale even for SB. Considering this is a tuning element in the drive train is everyone getting it right the first time AND is nobody making engine changes????
I think guys are apprehensive about used converters. I was but bought one used a few years back. Paid 425 for it. Last month it cost $516 to restall/rebuild for the new. Not to bad when a new one is $1350 from the guys that reworked it.
