340 or 440

Gotcha!

One thing for sure, you can put a lot of aluminum on the B/RB to get the weight down.

I used a 440 source W/P housing and pump on my 400. BIG weight savings there.



Somewhere on the site he talks about the weight difference and changing of components such as brakes also. It's a pretty informative page for someone looking to do the swap.
