I'm using a 400 block and a set of 906s just to check header clearance. The higher deck height on the RB block and raised exhaust ports on the 440-1s will just give it more clearance. I'm using the Milodon 31161 9qt pan Milodon dual line pick up and hoses (used) Milodon 21815 aluminum dual line oil pump Muscle Motor's pump cover, discovered that the oil pressure relief hole wasn't threaded deep enough. Neither the stock or the Milodon fitting will seat to the flange, easy fix just one more thing to fix but still like it) Muscle Motor's oil pan gasket (reusable rubber coated steel lined and has steel bosses at the pan bolt holes to keep you from over tightening) The lines don't touch the block, the pump, the motor plate or each other and there is room to run the dip stick tube between them. Anyone have any concerns with this set up? Do I have the lines routed right so the pump won't loose prime? 8012964-image.jpg (300 downloads) Wade Metzinger 918-809-0987 71 Cuda 9.28@145 -1s, Pglide 68 Cuda 10.64@124 1.45 60's 318->390 eddys Moparts discount code on WIX - moparts www.Filter1.com

Are you meaning that the Milodon pump's suction causes the supply lines to collapse? Or does the pump lose prime and sort of vapor locks even though they is oil in the lines it can't pull it? If your meaning that the lines collapse I may replace them with tephlon lined hoses just to be safe. I also run a Master Lube accumulator system that I use to pressurize the oil system prior to starting and it also keeps the system pressurized if and when the oil pump looses prime in my old system but was thinking I wouldn't have that issue with the way I'm routing the lines with this oil system.

Quote: Cavitation is the formation of vapour cavities in a liquid � i.e. small liquid-free zones ("bubbles" or "voids") � that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shockwave. I don't think the lines will ever collapse. In order to collapse there would have to be a restriction on the inlet such that the outlet flow would be greater. Since the feed line in the block is only around 1/2" and you have dual inlet hoses, I can't see where there'd be a restriction. And even then, I don't think an oil pump could generate enough suction to collapse -12 braided hose. Even the cavitation would likely only happen at the top end of the rpm scale - if it happens at all. Just my thoughts.

They are pre filters with screens in them.If something comes apart and gets in the oil pan,these will stop any large objects to get sucked into the oil pump and sent through the engine.They unscrew so you can check the screen for debris.

Maybe gravity will help keep at least one line full of oil when sitting and for startup may help get pump primed and pressure sooner. Last edited by mopdragster; 01/27/14 01:33 PM.

Helps make sure that oil stays in line so you do not loose prime, at least thats how I feel. "I am not ashamed to confess I am ignorant of what I do not know."

I set up my lines pretty much as Wade has his..with a little hump up to go above the pump... that way only the oil from the bottom of the hump to the pan can drain back and it always has oil in the pump and will always prime EDIT I use the pre filters also, just to try and save the pump if something lets go... the prefilters are a MUST on a dry sump pump... they cost way too much to let trash into the pump Last edited by MR_P_BODY; 01/27/14 03:22 PM.

Could be a crack in an oil passage running to the mains.
