single plane 360 intake wanted

An offset thermostat housing? Hummm,
FWIW, I have a TorkerII 360 from Edelbrock and it will except ethier large or small thermostat housings. The A/C brackets can, or should be able to be swapped out in order to move the pump over if need be.

Your newer A/C pump is a problem because it is longer right?
