Bypass hose for LA block with Magnum intake

I'm going to have to save for the Dyno. I just ordered a Dana, and will need a driveshaft, yoke, springs, etc. so that is setting me back some, but I see no reason to rush getting the engine in the car when the drivetrain wouldn't be able to put the power to the ground. I'll probably be ready to put the engine on the dyno in a month or 2.
