I know that there are 59* r3 blocks and 48* r3 blocks my questions are...

1 The degree just refers to the lifter bore, correct, the rest of the block is the same?

2 Are there different heights of the blocks?

3 Are all 48* blocks 340 mains?

4 Which of the 48* blocks are best for procharging?

Thanks, Clint

I have done a Procharged SB and on the next one I do It would be a 48* non-simese. The 48* gives you better valve train geometry if you have the heads that will allow you to do so.The reason I would go non-Simese is for the extra cooling around the cylinders if you intend to street drive it at all.

1 The degree just refers to the lifter bore, correct, the rest of the block is the same?

Yes

2 Are there different heights of the blocks?

Yes, 8.800"-9.600"

3 Are all 48* blocks 340 mains?

Not sure, most all 48 degree blocks will be 340 main but may take a 360 pan depending on the rear cap used.

4 Which of the 48* blocks are best for procharging?

All are great but the R3 with siamesed cylinder bores and 18 head bolts is the strongest. 9.600" deck is prefered to give more room for a dished piston with stroker crank.

clint get a tall deck 48deg siamese block,and u can procharge n fog it at the same time,,there mint blocks.

o yea and any w series head above the w5 requires 48deg block w7,w8,w9 etc

Would a person be able to use Edlebrocks or Indy-1 's on a 48* block? Whats to cost on a 48* tall deck block, roughly?

u can get a 48deg block,i see em all the time brandy new for about 2500,u will find em 2000 or so on diff web sites..and yes u can use a 59deg head on it,it requires some work though

some 9" decks had 2.250 mains (small ford) and 60 mm cam journals.
something noticable the cam is bigger than the crank.
also some were made with 47 degree lifter angle.
9" deck is cross drilled between siamised cylinders for additional cooling.
I would think they all are suitable for procharging, regardless of deck height.
depends on cost, tall deck hard to find?

If you have not yet bought a block you might even think about a new XR block from Kent Ritter like I just bought.

jeff nice block did it come with the lifter bushings?

Your getting more for your money and when we went to pick it up he helped us with a lot of other things while we were there.

Jeff that looks sweet, what was the cost if you don't mind me asking? You can pm me if you want about it. Thanks guys, keep the info coming, Clint

I think the cost before all the extras I ask for was right at 3,000. Kent was very helpful and told us if we ever need anything just call and if he can help he will.And it was a blast going on a tour threw all his shops.Before I bought anything I would take the time to call and talk to Kent and then make a choice thats best for you and your needs.

If you are buying one from a private party and not able to lay eyes on it , make sure that it has provisions for wet sump oiling if you intend to go down this road.
Some also came with no motor mounts and some had lightening holes in the bell housing area than may prove problematic for tech if you go drag racing with it.
Cam bores are for R-3 ony babbit bearings , 50 m.m. roller and 60 m.m. roller.
I haven't seen SBF mains , but it doesn't surprise me at all.
The book " How to build big inch small block MoPars " goes into a lot of R-3 details.
Shady Dell's web site has a lot of info on them and the W heads too.
I believe Indy 360's can be had with the extra head bolt bosses too.
I like what I am seeing from the Ritter camp.
Very nice indeed.

The wet sump oiling is a good thing to keep in mind.

Kent offers you many options,Wet or dry sump,All cam brgs ops.Tall or short deck.Not sure about the main options thats something I did not ask aboout.You can go with a std 10 bolt head,18bolt or Relocated for P7 heads.AND HE HAS PLENTY OF THOSE!!!Im not selling blocks for Kent but only trying to inform my fellow Mopar friend of a good thing.

2nd that.
Kent is the one to deal with.

Kent knows his stuff, and has plenty of it laying around.

That block is a masterpiece. And its done right the first time.

do you have any info on weight?
