I'm curious- I know that installation of an oil pan windage tray is recommended to keep oil from the spinning crankshaft, thus increasing horsepower, but, will this reduce needed oil splash to the cam, cylinder walls, etc. and cause premature wear? Thanks.

No not, at all. The oil that is splashed or slung up into the cylinders and elsewhere, comes off the crank after it passes through the bearings. I use a windage tray on every engine I build, even if it is not a high performance engine, just to help keep the crank from spinning in the oil.

The cam gets its oil from its local via oil pump,not the spinning crank.windage trays work great,as do oil pan trap doors and crank scrapers.hope this helps. 67rat member #199

I have a neat old '70 Pontiac engineering brochure that states: 'Does every high performance engine need a windage tray? No, every engine needs a windage tray!...' Assumining the engineers did their homework, the pickup is the all-important focal point. oil that flings off the crank (as opposed to being churned by it) will oil the piston pins, walls, and everything else it's supposed to.

Thanks for the comments- I'll be installing one during the rebuild.

You can still get the studs for the windage tray from Chevrolet. I like the teflon Moroso tray better than the curved Chevy one though. Tom
