Didn't talk about that specifically with Mike but that sounds (and from memory)!looks about right if not smaller). The fact that I'm pushrod oiling and its possible effect ( essentially none) on delivery pressure was the main topic. I just asked if the EDM could result in a noticeable drop in block gallery pressure. Level couldn't been an issue with a 9 1/2 qt system but I know I'm pushing too much ( much more than I need) oil up top. So restricting but not cutting off entirely the 2/4 feeds to the shafts seemed logical. My an fittings 90 degree fittings went from ~.370/.4375 to .475/>.550 ID
on the respective AN/NPT sides after porting, huge improvement in flow and there are 2 of them in series in and out of the Freightliner truck oil cooler.

The lightness combined with being able to get a nice long 7.65" 3/8 pushrods in it made the MRLs a slam dunk. The EDM feed works great on the 440" Small block and the offset intake cup really helped solve my W2 geometry issues on that motor.

Not gonna thread jack here,but glad to see you back Mr P !!
