Why did Mopar Performance stop doing the old Megablocks??? from like back in the 90s?

And then why did MP stop again when they started doing them again like 10 years ago?

Why did World Stop making the HEMI blocks???

Where is all that tooling? Those were all good blocks....werent they?

No money in it.

Don't care

Having worked for a foundry I can tell you that the dies/molds are not always owned by the entity actually selling the product, not always owned the by foundry, or whom ever. All depends on how the contract was written. I personally scrapped toyota GM ford and Chrysler dies. We held onto them for xxx amount of time then Scrapped them. Some does we’re owned by those car makers others by the foundry. All depends. Does not mean they are gone. Doesn’t mean they are still. Around either.

Where I worked we held onto VW oil pan dies for seven years after ceasing production. Then we scrapped them. On the other hand I am sure there are Dana 44 axle housing does still here.
If world or Mopar had the calls coming in for them and they owned the molds they could run some blocks.

Another variable - who did the machining - some foundries do it. Some don’t. Would Mopar have the tooling? Likely not but I would think world might.

Where can I find the book you wrote and where can I buy them?

Don't care

poly, you for one, has helped me immensely over the years to increase my understanding of how things work, and things to avoid while getting the most out of what one has. i, for one, thank you profusely ! keep this up as long as you are able, if possible.

Thanks

Back in either 1964 or 1965 a really good smart old timer mechanic(65 Yrs old+ back then) that had raced on Muroc dry lake before WW2 told me that there was nothing new being invented in cars, airplanes or train internal combustion engines since the early 1930s
I'm not sure when and exactly which year Wankle design the rotary motor but I seem to remember it being before WW2 also
Many parts and components have been improved since then like ignitions, rods, pistons, cam lobes, valve springs and so on
Keep testing and tuning to go faster

When Chrysler Corporation decided to stop producing bigblocks they scrapped the molds and sold leftover inventory for dirt cheap. Brand new 400 shortblocks in a crate, $400. 452 heads were something like $50 each, I am not remembering exactly.
So when they wanted to produce blocks again they had to build all new molds. At the time, this was widely publicized.

When the first batch was produced, thee were issues with casting quality and after a while Chrysler walked away from the deal, taking their molds (property) with them. At the time it seemed that World was bringing out a new block type every week. So Chrysler worked out a deal with World and started producing cast iron and aluminum blocks. But the deal ended somehow and Chrysler took their molds and left. A big difference this time is that Bill Mitchell managed to hang onto the aluminum molds. Maybe he bought them, maybe they were spares, but he is planning to offer aluminum Chrysler blocks for sale again. BMP has changed to a more modern foundry and has moved to a new facility and changed a lot of tooling. Maybe by late Summer we'll hear some good news. It doesn't seem like Chrysler is interested in the RB engine any more.

Others have tried and failed with replacement iron blocks. They must be hard to cast.

It's been reported here that the owner of Dart, Dick Maskin, was asked directly by a board member if he had plans for a Chrysler block and he replied that the volume just wasn't there.

Oh boy, not again. I've heard about empty promises for a long time now. SMH. If this is who I'm guessing it is...he retired...so I don't think we'll be hearing anything from him again..... And from what I understand, over time this became a normal method of handling inquiries. Sorry to hear that.

Hopefully somebody takes over this business, makes a great product with amazing margins driving them to constantly push improvements, and they make it basically forever. I'll also hope that they really enjoy managing it, because that alone will become a full time job. Can anyone guess the volume vs. tooling/ development cost? How many do you have to sell before you make money?

I talked to Bill Mitchell at PRI, and asked him about the aluminum Hemi blocks. He said that the whole thing is very complicated, much more that one would think. He didn't want to give details on that, or a timeframe, but he did not sound too optimistic.

Edelbrock is producing sbc and bbc blocks--- maybe someday mopar

Everyone would be just better off financially and mentally if they just put chevy engines in their mopars.

The R3 casting boxes have been located, but the holder obviously can’t let them go or produce anything without Fiats blessing.

As of a year or so... maybe longer, there were still mega blocks on backorder status. Funny they hadn’t axed them yet (code NS1...no longer in production).

My way cool parts manager retires next year. Maybe I’ll see if he’ll order like a 100 of them

This guys name was Dale. One of the board members here knew him and his shop in Detroit had machined some blocks for Mopar so he contacted him. He was told “ they are at the machining facility “. Yup, sure they are. Right over in the corner and they will never get done. I’ve got one world block and I’m not selling it anytime soon. Lol.

Maybe SBM, Maybe G3 Hemi, no BBMs market is too small.

Fiat has no interest in past engines, we have to push the aftermarket into it.

Marketing figured there would be a demand for About 700-800 G2 hemi blocks the 1st 2 years and drop off to 120-200 after that.
There was work on a tall deck G3 hemi block but it was decided that the engine would be too wide for any practical retrofit application, not to mention the Intake manifold issues
