Does this look like higher capacity pan?

[Bleep Bleep]

‘66 Hemi Satellite. First change. No ownership history or docs.

Service manual is 5 qts incl filter. I took between and 7-8 QTs out and was reading at the fill line (maybe another qt to be full)? =8-9?

Does the pan look aftermarket higher capacity?

Thanks!

Absolutely a deep pan, I vote aftermarket.’

Looks like modified stock pan to me, but definitely a plus to have more capacity.

Follow up question. Does a deep capacity pan translate to the motor running at a higher relative oil pressure?

No oil pressure doesn't care about 6 quarts or 8 quarts it just makes sure at HIGH RPM the pan isn't sucked dry..

Thanks. I wasn’t clear on it.

The SunPro oil pressure gauge idles at 75psi. I can’t be sure the gauge is correct but if it’s accurate is that too high?

Too high? Cold, no. What is warm idle pressure/45mph pressure? I like a 40-45lb idle warm, and 60-65 down the road. 75 at road speed wouldn't bother me.
That looks to be about a 7-8qt pan (+filter). I'd run 7qts, including filter. I would absolutely ignore the fill line on the dipstick.
The advantage of a deep pan is more capacity, and the oil can be farther away from the crank. Less windage, less power loss.
The disadvantage? Speed bumps.

Some would say it's too high but I have no issues with it. Probably just tight clearances with a high pressure pump. Could be heavy weight oil too.

That helps about watching the dipstick. Thanks!

Oh and also taking speed bumps at an angle.

Crowned roads also. I took out a deep pan on my '64 actually stopped the car and dug into the road. It was a Hamburger's Oil pan which lives on now in my friends 68 Charger..

I’d assume then the Baja 500 is out of the question.

Enginemasters did a test of a 600hp bbc with an aftermarket (nice pan, milodon) pan. 6 1/2 quart rated pan, plus one qt for filter.
Dyno'd it with eight quarts in it, and with five quarts (+1) in it.
5qts made 30 hp more than 8qts. AND had better topend oil pressure.

I watched that episode too and it was really impressive they were able to make more power by lowering the oil level in the engine. If I remember correctly they took it clear down to 4 Qts which didn't make any difference on power before they chickened out and quit. You wouldn't want to do that on a street car though.

Yeah, they mentioned that what you can get away with on a dyno, and in a street car, are two different things!

What I remember about the episode was a conclusion that oil flow is more critical than oil capacity.

I have seen this a lot over the years when drag racers are trying for the record. Drop all fluid levels to where they feel safe for 2 passes...

Is this a street car or drag car. Down side for a street car with a deep pan is hitting something like a dip or road hump. Gotta be careful with them.
