So auto makers got the piston sprayers from motorcycles. Most likely. They were to run higher compression & give some cooling effect. As wild one said crank splash is the issue/fix. Stock oil pump should be fine. We used hv oil pumps a few times ,& it only pumped all the oil to the top of the engine faster. The drain back is the same. Did one in a 80’s Ford that had a low oil sensor in the pan. Everytime you’d get on the freeway it would stall , because the pan was low from the hv pump. Then you’d start right back up & it was fine. Until high rpm again. Boy that was one to figure out. Put a stock oil pump back in problem solved . You can sometimes put a washer in with the spring & raise oil pressure on a stock pump. We did that to gm’s 3.8 v6. Back in 80-90’s. Crank splash seems to be the fix for hemi’s. Gen3 at 315k & going. 415k on truck .
