notmytarga -- interesting that you think the 2.7 will be ok with a loop cooler instead of a radiator style? have you had both? that would certainly be better for my budget.
Also do you think braided or solid lines the best? and,, did the kool kollar help any?

The Kool Kollar was a temporary solution until I rebuilt and burned-in my rings (and proved the rebuild was solid) - The Kollar is likely good for dropping a few degrees but that won't really solve a problem as much as it helps reduce temps a bit.

The rationale for skipping the radiator type heater was a combination of engine demand/need, period correctness and budget. I considered adding the lines and loop cooler to see how it ran, but no one was willing to give me their old loop cooler so the 28 tube was only a little more expensive. Using the Elephant finned lines and the 28 tube cooler, which is a bit more effective than the trombone loop cooler, I figured I would have a dramatic improvement over the no-external cooler setup that I had previous to the rebuild. Most of the improvement is because the external thermostat starts to open at 180 deg F and brings online the oil volume and large surface area of the lines and tubes. I haven't done a Thunderhill DE day yet when it was hot - but I can't get the gauge temps to read above 200 or so in any situation. I used an IR thermometer for tires and lines and the whole oil system after hot-laps was at 190-200 except for the oil tank which read 240 - I don't have a theory on that one yet other than I was measuring the temp of oil bypassing the thermostat.

Braided and flexible lines aren't going to provide cooling along their length - so your cooler(s) are going to do all the work - they need good airflow.

If I was going twin-plug or other high power setups or a 3.0 engine then max cooling would have been a demand. For track use a front spoiler mount is the only real solution short of Henry's two fender with airflow setup.
