yeah its worth it!
not too hard - it was a fun project
an rz motor in greta shape will fetch about a grand, a little more with all electronics
i have the rz tranny still - if I did it again, I would use the banshee bottom end
wiring sucks, but once its done - you appreciate it!
I actually may be parting mine out soon. If your interested in the motor PM me. I already have the exhasut flanges made, and I even have a set of Rocket pipes that will fit it (imagine that)
I have 3 banshees now - I want to be down to 1 banshee, and a 450 by the end of the year
