oil restrictors with high volume oil pump.
I am building a 1977 403, and I have read online a couple of times that when you put a high volume pump, or it may happen even with the standard volume, that all the oil in olds engines tends to run to the top of the motor and starves the bottom end. What do yall think about this topic and since the engine is not going to be used at the strip, strictly daily driver, should I use the oil resticors?

This is the list of all my mods. Well I have built one engine fo rmy ford truck,a nd been help of building anouther and on both of them we used high voume pumps just for the simple fact of better oil circulation.

I'm with olds64. At least the 5 qt from Milodon would be good. My first build was a stock pan with restrictors on a mild motor with a HV pump. Didn't need it, won't do it again.

Ok, so, what I have read is that unless you are running an engine at upwards of 5000 rpm, or high horsepower racing, then there is no need for oil restrictors. So therefore I could run a high volume pump, to ensure qaulity oiling, and a 5qt pan so I dont suck it dry. Anybody who doesnt think this is good please tell me otherwise.

If it's the one I'm looking at it says Hydraulic roller for a Pontiac. Maybe I'm mistake but that's what shows up when I click on the link. The picture is a flat tappet but the description is for a roller. It better be for $739.95!

Just my opinion but if you are running stock (snug) bearing clearances then the stock pump will be more than adequate, Just check pan to pickup clearance and having the pickup tacked in place is cheap insurance.
