Offenhauser Dual Port intake and AC compressor brackets to fit a 1982 318

Like the title says, I am looking for an Offenhauser dual port intake and the AC compressor brackets to fit a 1982 318 motor. I would also consider an Edelbrock SP2P intake. This is going on a truck. I am looking for low RPM torque and economy, not high RPM horsepower. I don't care if it is spreadbore or squarebore bolt pattern.

Cheaper the better, the closer to Tacoma, Washington, the better. I am on a tight budget. I am hoping to spend around $100 for both the intake and brackets, but I know that might not be possible.

Any leads appreciated.
