Hello all-
eh?! Ah the great white north! try huh instead! Good to see our
Canadian friends still apreciating American muscle.
LOL!! I'm not Canadian, though I did spend a lot of time north of Highway 8
in Wisconsin, and in Duluth, MN...I guess those Finns just rubbed off on me.
Scott,
But...which is better, a windage tray or a crank scraper? I'm guessing
both is overkill.
In an engine where maximum power is required, both are used. For the street,
the windage tray is usually sufficient.
Right...I thought you could get a rough idea of the oil gap using the
but what's a windage tray?
Bolts to the main cap bolts and fits between the oil pan and the rest of the
crankcase above it. It keeps the wind (windage, get it) created by the
spinning crank and rods from whipping the oil and foaming it at higher RPMs.
It also greatly cuts down on oil splash
Scott,
Um... Since I've never done a bottom end, I don't know. How much
*should* there be?
Directly from the Olds shop manual with minimum and maximum clearances:
Mains #1-4 = 0.0015 to 0.0031
Main #5 = 0.002 to 0.0034
Rods = 0.0008 to 0.0018

I guess with standard bearings I'd be well within specs. I found a couple
main brgs that didn't get tossed and one set was .001
Windage tray: If I am not mistaken, which I do believe I am not, is used to keep the oil down in the bottem of the pan so the pump can pick it up. Without it at very high rpms the crank throws the oil all around the pan and the pump could have trouble with starvation. Steven PignataroScott White
Hello all-
Just had a chat with my engine builder and I need some advice.
He's measured the rods and they're in the middle of spec. He's also
measured the crank which is on the narrow end of spec, leaving me with

bearings and go, just that my oil pressure, when hot,

0.002 is fine. What bearing clearance on the rods and mains were you
planning on running?

A high volume oil pump (extra 20%) would do a lot to
maintain oil pressure, probably enough. I wouldn't
mind fitting some -.001 bearings, as opposed to
grinding the crank. Grind when there is no other way.
