Man I hope that works the way you want! Sounds like it'd be a Brutal street car

That is exactly what I needed to see. Q Are all 59' blocks 10 head bolt only or can they have all 18 and use them on a 59' block. No biggie just curious. I think I have enough to go on now. I'll get back with pics and specs tomorrow for you experts to weigh in.
Thanks. I sure appreciate all of the help and knowledge these guys have given!!

Yessir, these People are some of the Best!
This reminds me of the old saying: u play the game, u take the chances. Kim
The trouble with MP race blocks are, there’s so many versions!!!
Here are some pictures of a 9.2 with my W2’s on top.
(I picked this up from @replicaracer43 a couple of weeks ago. Thank man! Great meeting you.)
In the pictures, you can see the short timing cover, the way the W2 intake was notched to fit the short deck and where standard head gasket sit in the deck.
I was lucky enough that replicaracer43 had the timing cover and intake to work with this other wise I’d have to walk away.
This particular block takes standard cam bearings as many other R3’s do. Bring a measuring tool.

what chances?
Getting something you can use or afford to use.
But that's why I came here and asked questions. So I can get it right.

Here is a close up of the 48….
Heck! I don’t blame ya! It’s easy to make a mistake with the R blocks.
There are 3 different deck heights and 2 cam angles for what 25 possible combinations? lol. And I know nothing about them soo wish me luck. I think I got enough info to get the right one but I'll be posting pics and asking more questions tomorrow. Same Bat channel. ;)
Best of luck!!!!

25 combos plus a few oddball blocks that never appeared in any parts catalogs…
Plus whatever fred next door did to it before you get it. lol. This one is supposed to be new and unmachined, 340 mains and std lifter angle 340 bore. The deck height is going to be the key if the rest is accurate.

Two atmospheres are better than one
I know a few guys that run roller cam bearings in high hp drag week type stuff, and our 410 small block ford in our race truck uses them and we race 1000s of miles at a time in Mexico. But I sure wouldn’t try doing it in a daily driver low rpm type of setting.

Yeah that’s the other factor… was it sent out not fully machined and something was custom spaced…do you have the Victor heads already?
I don't have the first answer and the answer is no on the victor heads. But if I get an R block victors are what I plan to run.
MoPar, AFAIK, did not do any custom bore spacing. I took his reference as a unbored cylinders in as he said, virgin block.
Get the numbers off the side of the block and anywhere else you can find them or any other glifs.

After looking for info about these blocks, I just realized the block I was offered was an R5 with the open deck. That seemed really strange to me when I was looking at it. Now I wonder what all special parts that would need.

Not wanting to detour this thread, but why and how does changing the lifter angle from 48 to 59 influence engine performance/durability? Asking as I have seen this discussed before and I don’t understand the basic background.
Thanks
I found this tell all about the blocks:
How to Build Mopar Engines for Performance: The Block Guide - Mopar DiY
When it looks like you are at the end of the article, keep scrolling down. There is more. A long article.
Thats awesome. Thank you!!
That article also explains and illustrates the 48 and 59 degree lifter angles.
