I have mine before the T. I find that in my climate - Sierra Nevada Foothills - the most significant benefit is the quick warm ups to minimum oil temps before flying. I suspect after the T, warm up would be a bit slower, as it would divert almost all pre warm up fluid through the heater core, but it might be worth trying. You would be essentially substituting a smaller radiator for the larger one. Until I put this one on my current Model IV, I had the radiator shutters which closed off the air flow through the core. My low temps here are typically well above freezing in winter. I also use the oil cooler shutters.
