PatriYacht - How did the Earls sandwich type work out for you? Was the installation cleaner than the Permacools and did they perform as intended? I think someone asked which 1 of the 2 listed works for GM based big blocks?
Thanks,
Doug

I am having the same problems with oil psi my main clearances are 1-.0026,.0023,.0022,.0023,.0029; rod clearance .0025-2.1989;2.1992-.0022. High volume pump mech gauge, k&n filter stock oil pwr steering cooler, motor was a 330hp gen V. Now running a balance ass. .030 forged dome pistons crane valve train 132561 cam gold race rockers, billet timing chain big valves large oval port heads intake and carb and headers. My oil psi cold 40wt is about 65-70lbs short runs carries about 52lbs long cruise 3800-4000rpm carry 42-44lbs. I have been complaining about this all summer and it didn't make a differnce running 30 wt, 20-50, or 40 wt it has all been the same.

Sounds like your oil cooler is just too small,I would buy a bigger cooler and replumb the lines to match. The stock cooler is just too small. It wouldn't hurt for you to pull the cooler first and make sure all the cooling passages are free and clear,if a considerable amount of them have debris keeping water from flowing thru them your cooler obviously wouldn't work well. Something else too is how much total timing are you running compared to your compression,too much timing short of detonatring your motor will heat oil up hotter from extra heat transmitted thru the pistons. The last thing is REPLACE your oil cooler bypass valves with new 30lb differential ones,its possible you have the weaker ones and your high volume pump is opening them allowing oil to bypass your filter and cooler,Smitty

Smitty,
Didn't see this thread the first time around. I will certainly be a big help to many people on the board. As usual, great job!
