Man those look GREAT and thanks for sharing. Looks like things may slowly be turning around for the Mopar guys wishing to step up their race programs.

On a factory cap there is a slot there. It's to get oil out of the back side of the main IIRC. With out going out and looking at a cap I'm going off memory.

Where did the older ones have problems? What should I be looking for, any idea?

Good question... all I know is the words "Ritter" and "porosity" seemed to go hand in hand on other posts about those blocks.

I believe WhiteDart would be a wealth of information in that area.

Verify.. every bolt hole is in the correct location and proper angle.. verify both the coolant side and oil side of every Passage.. if you're doing a Max effort deal verify the correct angle on every lifter.. hours were all over the place.. actually had to increase the lifter diameter to correct the issue.. oil drain backs definitely going to need to be improved.. if you were doing a wet sump
. But like I stated earlier from what I can see they definitely look better

On another note I'm not saying it's mandatory.. but I think bushing the lifters is a smart move with the way that he has drilled the oil Galley through the center of the lifter bore.. it's very easy to get in a situation where the lifter uncovers the oil Passage

I'll do all these things along with bushing the lifter deal, killing two birds with one stone. Kent Ritter suggested the bushing the lifter bores for a max deal. The machining done on the blocks I have has extremely nice lifter bores right now, not sure about angles but they all look real good.

It returns the front bay through a drilled hole that goes to the timing chain area and the other bays by a hole in the rear that returns to the oil pan area. What I mean by bays is the cam bearing saddles kind of create a bay in between each cam bearing saddle.

#2 through #5 have a channel that directs flow to the rear.

I'll try and take a picture this weekend.


Thanks. up

With the Limited oil return on the Block if you're doing a wet sump I would also recommend external drain Backs from the head to the oil pan this enables air to come up so oil can go down in other locations

Let me ask this, wet sump, what about drilling holes from the cam tunnel valley to the crankshaft, I know, I know, windage, it's an issue but is it really on a deal were you're not looking for every last HP?

I believe on a wet sump I would do a lot more work on oil return. I'll do that on one of the engines I'm going to build because it will be wet sump. I will look into all options but putting hole into the cam tunel to the crankshaft area would help. It might also help to return oil from the valley even though it is open in the back.

I will keep you guys posted.

Thanks for the post ! I injured my R-3 block a couple of weeks ago. This looks like a good option.

So, what’s the deal with the r3 blocks? Jegs lists a 9.025 deck 48 degree dry sump block for $2900. Says it will ship on the 23rd of this month. Is this not really available? Or is it just an undesirable configuration?

As for the ritter blocks... what ever became of the xr block that accepted the p7 heads/ cam?
A tall deck aliminum version of that would be absolutely fantastic to get your hands on.

We did exactly that... we opened up the cam tunnel to increase drain back. We are going to run a similar setup as White Dart using a Daily wet sump.

White Dart is a great source of help and information. I will be starting a thread as soon as ours starts going back together! Hopefully will be posting pictures in a few weeks good luck and if you need any help let us know.

It it's the P4876381AB block they show nothing at any warehouse or in dealer inventory.... JEGS has been famous for this. It's been awhile since I've searched part numbers but the last time I found a couple odd ball 59 degree and one or two 48 degree blocks in dealer inventory. Brett texted me part numbers to check here and there and I actually located a block in dealer inventory fairly close to his place. funny how that works out smile

...and fwiw that block listed also makes you go in search of the hard to find "Arrow" timing cover (was $400+ new), or belt drive.

P4876381AB is also listed on Jegs website, but again, none in any warehouse or dealer inventory.

I have ordered Mopar Performance parts from Jeg's and others only to fairly quickly get an email back, "Sorry we don't have any of these, they have been discontinued and cannot get them".

Also the big demand seems to be for tall deck (9.56) 59 degree blocks, not many out there.

First pic is the rear of the block

Third pic is the front of the block (timing chain area)

I have check ever head bolt hole, the lifter bores and angle, all the cam bores and main bores, so far everything checks out.

I’ll pressure check it at the machine shop before we deck, bore and hone and line hone.
