The value in these Venom engines is that collectors will fall all over themselves to find a new in box example like the one you have. My advice is leave it in the box, DO NOT RUN IT. If you do run it you will distroy it's value to a collector.

Absolutely!
A new-in-box never run Venom is in the $300+ range.

A pristine looking "bench run only" Venom in the box as originally packed recently brought $136.50

I DON'T question whether a Venom is a rare and collectable engine - only the number of them that were likely made.
