Below is the setup on my '66 GTO. It's a C4 Corvette unit (made by Modine) attached to a 90deg adapter via a simple adapter plate on a Firebird long-branch adapter. The hoses connect to the heater nipple on the RH head (although mine takes water from both heads) and then to the heater core. The switch (used to) control the electric fuel pump and also turn on an oil pressure idiot light (with rally gauges and solid rollers, you can't hear/easily notice if there's low oil pressure). This cooler also allows (forces?) the use of SBC oil filters. Unfortunately, with Doug's headers I have to use a shorter filter than that PF-35L (it worked well with H-O Racing's Tri-Y headers). If you want a CAD file of the adapter plate, shoot me a PM.

The late 90s Chevy trucks with a towing package had a similar oil cooler. At least my 97 sure does.
