I'm sure you are going to disassemble and check clearances, etc, before installing it. I know I would!
I most defintely will be leaving this one as built. The builder for Mopar put 15 hrs of dyno time on it and tore it down for inspection afterwards. This are nice pieces!!
The retail price in Canada is almost $68,000.00 so they aren't cheap by any means.
It had 850 hp on gasoline but is set up for alcohol. With the required change in blower pulley and the alcohol carberators mounted on top it should be well over 1,000 hp.
