Engine Oil Cooler Install

Those Setrab oil coolers offer through Pegasus are actually pretty good; I'd just switch to the Pro-Line STD 1-series (not the slimmer SLM ones) that are tall and have more tubes for lower pressure drop. I'd get something in the 300-400 HP rated range to compensate for that block filling. (The larger B&M's look pretty similar, but they don't publish pressure drop ratings.)
