Hello,has anyone heard if there will be an aftermarket RB iron block made again in the near future? The Muscle Motors one looked promising but I've heard they went out of business and were bought out. The new people that took it over have a facebook page, and are taking money with an 8 week delivery time frame. Under the circumstances I see that as a gamble.I guess I could use Indy but they are $3800+ and you have to pay extra for billet caps and finish machining from what I understand on their website. I understand the days of a $2600. RB is long gone, but I find it hard to believe there is no market for something half affordable to the average racer. Thanks in advance.

It's going to take a lot of looking, plus with the Canadian peso you will pay dearly if can find one.

If it was me I'd call the guys at Best Machine and see what they tell you to do.

I have the peso's covered, but it seems they are made of unobtainium!

Tony is making it tough to try to do anything serious and remain loyal at the same time. Aftermarket is not picking up the slack.

Indy's blocks are 5k now. You can call Chicago Connection for an iron block. They are a distributor of the block MM was selling.

I ordered a compact graphite iron 4.500 bore wedge block from Billy Mitchells (SP?) company when they owned or where in partners with World Products, I waited a long time before they cancelled making them due to not having enough orders.
I had placed a order with Dave Koffel for a Koleno high nickel cast grey iron block and ended up cancelling it when he called to say it was ready to ship, stupid me realcrazy One in the hand is way better than one on order up
I placed another order with Dave later two years later and got it several years later up Dave had said that casting iron Mopar race blocks was a black art according to what he had seen and heard while working at Chrysler and seen later on both the Koleno and World iron blocks work
I have talk to the guys at Chicago Connection for another iron block but I think I will wait until they have several bunches machined and in use before stepping forward on them work twocents

The casting problem has always been they want to use one casting for a Hemi or a wedge block. You would think they would have figured out by now they need two different patterns and core molds.

I have a (The Block) that I bought from Muscle Motors. Although MM was involved in testing the blocks, they were not making them. The sourcing of these blocks has not changed. They are available from several vendors.

Have you used it yet? If so how was it and how much extra machine work was needed to make it useable for your deal?
Last thing is it a RB or B wedge or a Hemi block and what size bore was it to start with?
I'm still in the market for another good cast iron, not aluminum, race block work
Thanks in advance for your help on this up

Its a RB 505. I went 0.030 over as it will be a street engine.

Can't comment on the machining as I bought it as an assembled shortblock. I hope to get the motor fully assembled and on the dyno by the end of the year or very early next year.

I'm going to assume that it is bored to 4.350 with a 4.250 stroke, is that correct?

I didn't put it in the post cause I didn't want to guess but quite sure that is correct. It is a 4.25 stroke - stock bore 0.030 over.

Don't quite remember but if you search the subject here on Moparts they have been listed.

I do believe Chicago Connection was one.

Just curious, as to why bother with a iron block when aluminum blocks are available as a option? I can see if you are running a class that requires iron.

Aluminum blocks do not keep the cylinder as round as a iron block will when running shruggy Hence they make less HP N/A or with a power adder than a cast grey iron block will, the Compact Graphite iron blocks are even better than cast grey iron thumbs scope

You could always HardBlock the aluminum block to keep it from moving around. I know people that have done it.
