The issue is not 606 or 603, the issue is deep-sump G oil pan or shallow sedan pan. The sedan pan works but is not suitable for off-road driving. When the deep sump is used, the longer oil pump must be used to match. Pressures are less of an issue unless you are building a drift racer. My long neck 606a oil pump has "35" embossed on the housing, but i have never heard of anyone having oil starvation issues with a 25 or higher pump.
