I have a 5.9 with chinese dual pattern intake. The water neck is in the way of AC compressor. I thought I could cut the right rear lug off the compressor but a hole opened up.

Anyone have a solution?

Weld the hole shut on the compressor and file it smooth.

Can you get one of those aftermarket swivel thermostat housings and a different upper radiator hose and reroute it off to the passenger side?

I dont know if a swivel housing would even help.

it'd take a bit of fabbing but what about shifting the compressor over a bit?

I steel plate. Thats an idea

Had the clearance issue with an Edelbrock LD4B and the VIntage Air bracket for a Sanden Compressor. Solved it with an Edelbrock Performer intake that had the thermostat housing more offset to the driver side. Cleared, just barely, but cleared.
Downside is the LD4B is a much better intake.

The Magnum Edelbrock Intake and the now discontinued Mopar intake
have the filler neck in the correct location on the passenger side

The cheap intakes do not

You could take a factory magnum thermostat housing and re-angle the housing to lean away from the compressor.

This right here. The angle is very slight but noticeable. New ones are cheap at the part stores. If going used, check for pitting on the mating surfaces.

Ill look at that but Im leaning on getting an edelbrock intake and selling this one. Piss me off
