alex wrote:Grumpy I read the thread on windage trays and I,m rather interested in installing one but I won,t be installing ARP main cap studs or getting the block line honed, so obviously Im looking to install a windage screen thats part of the oil pan itself, I really don,t want to spend $80 on the windage screen and want to look at options, any ideas?


There's lots of options and careful measurement and a bit of thought goes a long way here!
the oil level drops by about 2 quarts in a running engine as theres about 2 quarts circulating in the oil passages and in the heads and lifter gallery when its operating, I generally look to have the oil level about 1/2" up on the main caps while the engines sitting, and because most engine sit in the car frame at an angle I'll point out that 1/2" up on the main cap is measured on the rear main cap,and the arc of the windage tray should be just about 1/8" larger in diam. than the rotating assembly arc. so thats where in the oil pan the windage screen needs to be bolted or welded
but I also use a windage screen and crank scraper to control oil return rates to the sump.
you might want to consider installing a windage tray and oil accumulator ,
the pictures below may be useful to give you ideas, and rolling perforated screen on a gallon paint can can help bend it to shape, tin snips, a plazma cutter or a dremel can be used to cut screen

materials required are easily obtained, careful measuring and fabrication can produce a very effective windage screen as a component part of the oil pan design.

perforated steel from larger speakers, computer mounts etc can be salvaged and reused for fabricating windage screens if you have some ingenuity skills

IT MAY HELP TO REMIND YOU HERE WHAT A WINDAGE TRAY DOES
it basically forced the rotating assembly to act like a huge and very effective impeller that pushes oil in the lower crank case back into the sump as it forms an oil shearing semi porous barrier that separated and protected the oil in the sump,from the hurricane force winds the spinning crank assembly produces but still allows the centrifugal forces to throw trapped by the spinning assembly into the sump.

if you do build a custom windage screen make sure its mounted so it won,t be closer than about 1/8th inch from the arc of the rotating assembly, or further than about 3/16" so it actually works as intended, and the dip stick slides in, the block so it lines up with one of the ,main caps OUTSIDE the windage screen , but inside the oil pan,so the extended dipstick when inserted CAN NOT contact the rotating assembly, the reason should be obvious, if the rotating assembly contacts the dip stick your going to have at an absolute minimum one hell of a noisy engine but more likely a busted dipstick and the need to pull the oil pan and remove a bunch of metallic debris that USED TOO BE a dip stick and possibly replace an oil pump and bearings
(one more reason MAGNETS in the corners or the oil pan sump and an oil pump pick-up with a screen that limits the crap the oil pump can ingest are a good idea)

I bought a 1965-1969 Pontiac 389-421-400-428 Full length windage tray for $20 Grumpy.
I think it may work in the Olds 425 oil pan with some minor trimming.
I modify it at will for better oil retun.
Possibly mount to the pan with welded studs.
The Factory Pontiac windage trays are real strong stampings.
Not a perfect design but better than most.
Hard to find today & price was right. Only 1 on fleabay.
Also bought New Set of Valves for the 425.
NOS TRW. Make my Valvejob done by me go easy.
Good price deal too.

But its straight & unmodified the windage tray.
Like to get Crower Enduro Stainless rocker arms.
Very precision made & Quiet .
My spring loads are not that high & can get by with stock rockers for now.
Trying to scrape up extra $$ to get the good stuff.
Otherwise have all to build it up.
Ford 302-351 Winsdor rockers work on Olds V8 engines. 1.6 ratio stock.
