The factory ‘70 and later Eldorado pickup is 0.625” ID, but it has a bend coming out of the pickup screen that is seriously crushed down. A 0.875” ID tube would me a tremendous upgrade. I can’t imagine going any bigger than that without just going to a belt driven pump.

Was just being snide. He "may" have had the Holdener engine with "stock" oil system. What about the NA 1000 crate engine? "Stock" also? What about doing these things with the CaCo cast pan?

He said the stock system is good for 1500hp. Courtney’s words.

Must be something to it. He's to old to play the "sellem shit every year" scam.
B

But what did he mean by ‘stock’?
That's what I'm asking.

On you tube Ive seen a CadCompany engine with a belt driven external pump. It was on the 900hp engine. Those 3.250 full groove mains flow a lot of oil. The details of the 900hp engine components wernt in the video.

Test in progress. 1.125 i.d. tube
I take it your set-up won't work with this. Really want to go with the aluminum pan.

Thats a nice pan. If you can run your engine on a test stand to full temperature and monitor oil pressure then youll know before installing in vehicle.The
875 i.d. tube may fit. I was told years ago that the larger tube wont fit. I never take anyones word for final outcome. Modify the pan on oil pump pickup tube side. Use aluminum tube with section cut off along length. Courtney modifide the aluminum valve covers for the stream liner. Make pan for best oil system flow. Then fit to cross member. Mig aluminum. Bolt the pan down to an engine block with no gaskets when welding. At the minimum make a high flow screen. Schumann oil systems did research on the screens and found massive restriction with those factory screen. Your using hydraulic rollers? I found out that any preload on the Howards Cams Cad500 hyd roller lifters caused them to pumpup and what a sound that makes! 1/4 max turn.
