Jerry, I did the external spin on filter adaptation as described in the tech section here on Stovebolt. Blocked off the oil galley, ran it outside to the filter, then back into the galley towards the rear off the engine. Oil pressure pops to 35 lbs. within 2-3 seconds of start-up. I have 4000 miles on this build and its quiet as the first day of the rebuild. I guess I won't worry about the oil cooler anymore. This is a car 235 with hydra. lifters also.
Thank you
Sharon
