Yeah, I realize that, I was just saying. Anyway, I'm not worried about making every last little horsepower, I'm more interested in longevity.

Haven't ever tried the two pick ups yet. Don't know about pan getting sucked dry...this block had oiling mods done to it. orifices drilled out, large deep chamfer to the crank, balanced bottom end , all new parts. Have built new motors with high dollar pans and waste the bearings in them in no time. I know alot of the little tricks to helping the SB live butstill, its up to GOD if they live.

If its a stock truck pan. Thats your problem.
I have ran and seen regular old run of the mill Milodon and Moroso center sump pans run into the 9s with a stock pump with the usual mods.
I had a 88 Dakota pickup with a truck pan on it. Run it into the 11s with no problems but after I got into the 10s and eventually 9s there was no way that would have worked with no baffles.
I also have ran rear sump pans on my dragsters and had oil control problems in the shut down.
Are you watching your oil pressure gauge after you lift at the finish?
I bet its dropping or going to zero.

Sounds like you have built a lot of engines off your eyeball and feel. I think ya need, and I mean NEED to get some mics, and bore guages and check things out.
I am running a precision pump thats blueprinted, and polished inside. My block it opened up on all the oil galleys, Ive spent hours with a diegrinder, and a flap wheel blending all my return holes, I have painted the inside with glyptol to aid in returning oil, have screens epoxied in the valley to keep any broken parts from going down farther than I like, and I have made sure all my clearances are dead on, not close, but dead on what my machinist recomended for the oil I run.
I run a charlies 9 qt pan, and with 9qts in it it still reads 1 qt low. I dont run it brimmed off, and I have never had an oil psi issue. If anything im a bit on the high side, but at temp its reading 85 on higher rpm, and 30 at idle.
Im a solid roller set up, and I have pleanty of oil to my rockers and pushrod cups.
Not to sound like a dick, but I think Id be checking my eyes, and feelers, or getting some tools to make sure you didnt miss something.

Mics and bore gauges is what my machine shops are for. payin good money to ensure stuff is right from the beginning

Famous last words from many people.
I NEVER trust anyone on their work. I check every rod, every pin bushing, everything with my own measurments. That way the machinist cant say, "you should have checked it"...
This is what pisses me off with some of these posts. You have a history of engine failure, and you dont want to measure things after they are machined. Yes you may have them right on, but ya know then you may have a good GM machinist, and a crappy mopar machinist. Why be a bone head?

I.m with you on this one,I deal with a very rep machine shop and on a few occasions I have had to send things back after double checking there work.

I would start here..... 
 Yep, the problem has been discovered  .

My thread was to solicit info or opinions about the 2 pick up pump. If anyone's got thoughts please hollar. All responses appreciated. My stuff has put me in the winners circle. I've gone 9.70's with a 418. Wouldn't have 30 years of racing to me credit if I was a Jethro Bo Dean

Then You of all people SHOULD understand where we are comeing from on the aspect of proper measurments, and specs. As for the twin pickup deal, it should work, but as stated you are sucking the pan dry as is with a single pickup, so i dont see the puckup as the issue. Might just get a deeper pan, and more copacity.

Myself I would pass on the double pick ups... as
stated, if one sucks air its done... I havent ever
had a problem with a single stock pick up... I do
extend them when I deepen the pans plus I install
baffles in the pan to keep the oil down there instead
of rolling up the back wall or the front on braking

But how many more times would you have been in the winner's circle and/or possibly gone even faster if your engines would have stayed together for a "reasonable" amount of time? (Not to mention how much money you could have saved.) Being a good driver or tuner doesn't matter much if the engine doesn't run.
There is probably 300 years of racing and engine building experience in this thread telling you that your problem is solvable without experimenting with "trick" parts. If you have lost a lot of engines in the last 30 years, then you may very well have been doing something wrong. It might be by just a little bit, which would explain why some may not have had problems. But it's that "little bit" one way or the other that will make the difference. Measuring things all but eliminates that variable.
Get all the measurements and clearances checked and get a good baffled pan. What can it hurt?

It's already been said, but I'll repeat it: If the pan goes dry with one pick up, adding another isn't the answer. You have a problem(s) elsewhere. Please consider the constructive critism I'm about to offer. You say the clearances were obtained by "look" (how's that possible) and "feel"...and you also say you've had many that have died due to lack of oil/oil starvation. Me thinks the two might have something in common...
I say that, simply because MANY have screwed together a SBM with common (BAFFLED pan, Melling pump) parts, no or few oiling mods and they have lived normal healthy lives.

The MP engine book shows a kit car pump that had 2 lines going to 1 pickup.
See attach.

Two pickups = bad idea and totally unnecessary IMO. You need to look else where for your oiling problems.
