Air intake clearance

I've got a LQ4 installed in my 72 and am trying to get a cold air intake set up. I'm using a Edelbrock Pro Flow intake and with the downward angle of the intake and throttle body I have very little room for the 90 off of the TB. I am using the factory fan and shroud. I bought a Air Raid tubing kit hoping to cut the 90 short enough to clear the fan but it's not going to work. The battery has been moved to the drivers side and intake is going to the passenger.

I have seen a 90 that is really short and flattens out to keep the flow but I can't seem to find one on the internet Does anyone know a source for one or am I going to have to ditch the fan and cut the shroud?

This is a kit that I bought on Ebay ( cheap) . I had to buy an extra 90. This is a 2003 4.8 with stock fan , I don't have a shroud on it yet .

Re: Air intake clearance

Here is a better look at the engine bay. Not sure if you can see the downward angle of the throttle body opening.

Or move the engine back. It looks like it's awfully far forward.
