Raff,I hope your tranny is up to the task. When I went from our 493 to 572 we started to tear up the front planetary(multiple times).This is launching off of a brake at 4500 rpm. Got a little smarter and After a bunch of A&A parts we got it to hold together. Big motor= lots of torque!
My 572 with Alum rods oil pressure is 80 cold and after a pass is down to 28-30psi at about 160-180 temp. I do have an adjustable pressure spring and single oil line that has worked fine to 7000 for the past 8 years.

Hi ! Thanks for the info ! i have adjusted now the screw 2 turn and oil pressure at 180f is 40 at idle and 80 at over 3000... i think is good with aluminium billet pump and single External line , i have also a dual line kit....but very hard install with stock engine mounts ... this is my trans specs : billet steel front drum , 5 gear planetary front and rear front and rear solid bands Full Manual v body .. no trans brake ..billet pistons with 4.2 lever big aluminium oil pan 5500 converter
