I have a snap on drill, and on high its got 80 psi cold. On low its got 73 psi cold with Brad Penn 20w50. My buddy thinks its too much. I have solid roller, and harland sharps. Stroker so RPM isnt gonna be over 7200. At least I dont think Ill ever need to go there. Whats your thoughts? KAsey

I can run a 10w30 or 10w40 oil too. This is with a pretty fast high torque 1/2" snap on drill. Its got nuts for sure. I can pull the pan and "adjust" it, but man I really dont want to break this seal, Its sealed up REALLY nice. Kasey

And that is with the engine spinning by hand with a long 1/2 " ratchet. I did pause at the rocker oiling hole, and made sure al rockers has good oil, and it was a little less there. Its a precision blueprinted pump, and I didnt mess with it, its how they sent it too me. Kasey

That's not a very accurate test of oil pressure. Gotta get it up to temp and get some time on it before the oil pressure lines out. You will almost always see a 10+ psi drop from a brand spankin new just fired motor to one with a 1000 miles or so on it. I sure woulbn't worry about it at this point in time. Fastest 300

Im getting really excited now. Im thinking of calling ARP and ordering some 3/8 studs for the rocker arms. They make me feel better running them.

I had to make 3/8 adapters for my heads and that pushed me headers out a bit and I dont know if a K&N filter will fit. Ill buy one and check. I know the Napa GOld filters have a thick case also.

But I too feel that this is not much of an indicator of the pressure in the actual running engine with hot oil. Of course if I had to "go like hell" and only Got 30 PSI I would be worried.

Its funny, When a person who hasnt followed your build read this, he would swear your 501 is a big block...

Most our drills spin at 1800/2400 RPM and most cars idle at 900/1000 RPM.80 PSI on a drill is not a issue.If it was a lot less,I would be looking for a problem.

So it's 4800 engine speed and it's usually about 20psi higher turning the engine by hand to oil the top end on the stand than once it's running on the stand. I think you're fine. Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Spinning the drill with out the primer rod, it spins fast of course, but once the pump got pressure up, it just boggs my drill way down. At any rate, my new 499 on the floor, hooked to the trans, spinning the engine over with the starter hooked up and plugs out, it was 85 psi on the gauge. Once I started the engine up in the car, and broke it in, it was 75 psi hot at 2k and 45 at 850 rpms. It goes to 85 psi at 6k. I just run straight valvoline vr1 30w. I was considering putting a stock pump on. I installed an HV since I had an 8 qt pan and roller rockers with a solid cam. I feel it is too much pressure at the higher rpms. I street drive this engine
