patrick motor sport front oil cooler question, Is one oil line longer then the other. I need to cut the line. Options

[buck toenges]

So I am now getting ready to install the oil lines to my front oil cooler. Unfortunately the kit comes with one 22ft oil line. I would like to cut the line in two before I start threading the needle (oil lines) through the car. Does anybody know how long the lines need to be? Is one line is longer then the other?

I did notice that AA has a kit that has 2 oil lines. Does anybody know how long are those lines? (DR. hint..hint).

I also need to know how much oil I need to add with the addition of the front oil cooler. I have been told 3-4 qts. I plan to add the oil as the oil gets hot.

Finally does it matter if the hot oil from the engine enter the top or bottom of the oil cooler?

Thaks,
Buck

I’ve read almost every 6 conversion and engine upgrade thread that exists and the common theme seems to be that no matter where the thermostat is placed, it works. Seems to go for street cars and track cars.

Off the top of my head, I might have this wrong but doesn’t the engine pull from the oil tank anyway. So if the tank has ~9 quarts, that’s a lot of cold oil compared to the pint of cold oil that is in the lines up to the thermostat near the cooler.

The oil *always* flows, the thermostat doesn't actually close the line to the cooler, it closes the bypass when hot.
Which also means that the thermostat failure mode is always full flow to the cooler.

Yes, the engine pulls from the tank but on the other side the engine constantly pushes oil out of the engine and into the lines.
If the thermostat is close to the engine, the oil only has a short way to go from engine to thermostat and if it isn't hot enough it goes right back into the tank.

If the thermostat is in the front trunk the engine has to push all that cold oil through the supply line, through the bypass and back through the return line.

So does the ~ 12’ of extra line when the thermostat is placed up front, make a significant difference to the function of the engine or is it just a different setup with the same result? I have never seen a conclusion either way.
