And that's why I love oil-to-water coolers like they used on 4th gen TA's with manual trans and C4 Corvettes.
On a cold start, the water heats faster than the oil which causes the cooler to actually warm the oil. After warmup, it's the opposite situation.
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.
