Thanks for the replies. I am ditching the existing Moroso pan evac set up for the vacuum pump. This engine is a 499 lo deck with -1 heads and Harland Sharp rockers. My 582 BBC that was in my dragster had a breather style inlet on top of the valve cover and it provided almost no oil to the pump at all. My routine with that one was to squirt some oil in it every race day. I guess no matter where it goes, if I have too much oil going to the puke tank I will baffle it. Thanks!
