"To gasket or not to gasket?  That is the question".

Gasket, although they're a pain to line up with the motor in the car!

Gasket !  put a thin dab of Permatex on the gasket  to stick it to the pump, then install.

Just in case you're wondering WHY I asked.............

I'm getting tired of all these experts telling us to eliminate gaskets or use silicone......Ma Mopar paid big bux to her engineers to figure out what would be best (cars leaking oil on the showroom floor would be a real sales leader!) and anyone doing a stock or near stock build should not follow race engine builders blindly.....those engines get torn down so often of course they don't want to use gaskets! I use gaskets and glue....no leakers here!

They have a term for this......"re-inventing the wheel"..... (http://www.moparfins.com/forum/smileys/smiley19.gif)

That little O ring only seals the shaft, but not the suction and pressure holes in the pump and block -- use the gasket and be worry free.

Good points - both of you.

That one guy stating that he could not find the proper gasket is an interesting comment (in the link), but not uncommon.  I have found the same with AMC stuff.  I wanted a timing chain cover gasket only, but had to purchase an entire top-end set to get it.   When I put a new oil pump on my 440 it came with a new gasket.  I did not go and look for just that gasket, but I'd bet it's included in a top-end kit as well.

Yeah  What they said. . . . .
 
Shame on you for going someplace else

I googled high and low for that stupid gasket.  The only hit to come up was 440 Source.  I bought three of them.  You never know...........

I love these videos going around of these morons doing dyno pulls.  The swap out a chip and put on a fart can and do 3 straight pulls to a gazillion RPMs.  * POOF* one rice engine down the toilet....

It seems they don't know what the red line is for on their tachometer...maybe they think they're supposed to rev it all the way to the end?

Well slightly of topic.
High volume or high pressure oil pumps??
I am shopping for the BoaB's 383.
Thanks

Personally, I think the best value all around is the Melling high volume.  Feel free to argue with me. The Moroso pumps are relabeled Mellings.  If you do go with the Melling HV, get the bolt kit also as the stock bolts are too short.
Like the stitcher man said earlier, HP is not good on a street engine.

He says that, but why?
 
I've run a HP/HV on several motors with no problems.  It moves more oil through the journals and keeps them cooler.
 
I'll check the down sides in 100K or 2 when I tear down Polaraco.

I've heard it from others,  not just the stitcher man.  I'm just going with the consensus...

The only problem I am aware of with an HV pump in a big block id oil starvation.  Sometimes too much oil stays up in the top and the sump is too low for the pickup.  The solution is run it a quart over to be sure.
 
I run Polaraco a quart over. . . .
 
If there was an issue with HV/HP pumps, they wouldn't be so easy to get

You're not listening. (http://www.moparfins.com/forum/smileys/smiley12.gif)
I said HP may be too much for street engines.  Not HV.
 
As far as "wouldn't be so easy to get...",
day-go spark plug wires are easy to get, too.  Would you run those?

There is a HP/HV pump also.
 
That is what I am using
