I can remember two actual complaints...some had paper thin spots that could be broken through easily with a sharp object.
(So that means a whole lot more than two were really out there)

The response from the ivory tower was, the product was developed using FEA, and the thin areas in the mains were, at that time, considered deliberate.

I was also given examples of several builders who deliberately opened up/machined away those thin areas which I was told was for a reduction in Windage losses.

This wasn't a debatable topic at that time, and these are not my ideas. The corporate Gods had spoken, LOL.
I'm just the messenger so don't shoot.

for the price charged, I'd prefer overbuilt rather than under.


If the block was computer designed, what strength was specified? Like peak cylinder pressure, torque etc.

The answer falls under the blanket of "proprietary information".

Note I'm not saying I agree with it, but this is what I was presented with at that time.

I e-mailed Bill Mitchell and got an immediate reply: These new blocks have been proven to 2000 HP with no issues.

Sounds strong enough for me, and comes without the Indy attitude, and the extra $1500 for a KB that you can't get anyway.

I have a new KB 4.500" bore hemi block (probably 7 years old) and a new Bill Mitchell 4.500" hemi block that I might sell soon. Also 2 NOS iron hemi blocks if anybody needs them. One is 4.500" bore mega block and the other is a 4.19" no lifter machining block. I guess like they use for Super Stock or other high output applications so they can spread the lifters. I live out in the country and am thinking about taking an extended leave of absence and getting a little antsy about leaving such easy to steal items laying out there while I'm gone.

I paid $6,000 for the SS block and I think $6,000 for the KB with freight and I believe $5,800 for the Bill Mitchell. I'm willing to sell them for what I paid. Someone already bought the other block.

There is no blocks to be had right now, KB or world. Indy doesn't either, and id rather spectate then give them money for that block that has issues staying cool and returning oil to pan.

Bill Mitchell had Hemi and Wedge aluminum blocks at PRI. World did not have an iron block there and an inquiry resulted in "how do you know about that?" and an explanation that they are in the works. No Bulldogs in sight anywhere that I saw.


If the results don't match the theory, change the theory.

Probably parts paid for and not delivered. A buddy of mine almost sent money a year ago, based on the information he was given (not by Bulldog) that the issues were resolved, others had received blocks in a timely fashion and a block was available for inspection at PRI.

He got cold feet .

So are you saying World is going to cast Iron Hemi and Wedge blocks?

That's the scuttlebutt. No involvement from Tony. Seems to be early in the process. Guy I went with talked to them. I'll have to ask him if they said anything about an ETA.

That must be really late in the day, given the lack of people. Place was packed all 3 days.

Those are the main doors at the front of the hall. That's a high traffic area and the doors are closed. I'd like to know the details.
