What is it with these blocks recently cast going out into the market place with porous, core shift and or hairline cracks?

Back in 2012, a friend of mine purchased a brand new Mopar Hemi block from Chrysler for his Hemi Super Bee project. His receipt indicates that the (Quality control or lack thereof)cleared the block and gave it a clean bill of health to be sold in 2011.

He's finally been able to acquire all the part$ needed along with the fund$ to build the bad boy through a reputable Hemi builder here and now finds out that the block is a mess.

So what gives?

Is he stuck with it all?

He still has his purchase receipt from the dealer that he bought it from.

Is this what most new Hemi builders are facing these days along with hideous stories of aftermarket suppliers/casting facilities not delivering on their promises?

Is there such a hole in the supply and demand that one has to look for a stock old seasoned block with his/her fingers crossed?

Gee, short from just giving up on the hobby, my friend has now hinted on just going with an old seasoned and standard Wedge.

What a shame we face in this day and time. The fact that we as a unique brand can't get a decent honest to goodness BLOCK and a date in this century to actually receive it.

Typical Chrysler,Westgate and others had those porous blocks that had leaks in the oil galleys,some external to the inside and some to the water jackets.It's best to buy aftermarket blocks like Bill Mitchels and others but they also have some minor issues,mostly machine work that needs corrections.The old seasoned blocks on the internet is even a worst crapshoot.

Give up on the hobby or give up on the brand?

Tony doesn't care about any of this. When a person can make a phone call, give 'em a credit card number and 3 days later have a new 1000HP 565 sitting on the floor for $17k, you have to think about it. Do you really want to deal with a bunch of used up, hand me down, patched up stuff or "new" parts that require major machine work or repairs to be usable?

Are there any quality issues with KB stuff?

Almost any block you buy will have issues. The old stuff is really used up..Find someone who stands by their stuff and spend the money.

Who is that one out of all the current vendors that stands by their work?

you can have 100% trust in the quality of any block
you buy from Bob George

Numerous folks told me as soon as I ordered my R3 block do not sit on it! Get it checked! thankfully it was all good.

I only had 2 issues w/ my KB hemi block. 1st was a couple of the lifter bores were a little tight. Easily fixed w/ a light honing. 2nd was the front counterweight on my 4.5" stroke Callies crank actually hit some of the webbing in the block and needed a little clearancing. Not a big deal at all, but did surprise me. Glad I caught it in the mockup stage. The rods all cleared just fine.
Naturally there was a lot of clearancing to be done for the pushrods, but that's to be expected.

They are almost ready to go right off the truck but you have to plan ahead. If you want one for NEXT year order it today. Not a big deal for some but a big issue for the "I want it tomorrow crew". The Indy blocks are nice too but be prepared to spend more money on it before its race ready.

I actually just got off the phone w/ HP Performance and they ARE making blocks. They got restarted recently after being down for a couple years after their initial launch...that was the last I'd heard and didn't know they were up and running again.
The blocks are aluminum, hemi or wedge, tall deck or low deck. None in stock b/c they go out as fast as he gets them in. Should have more available to ship in about 3 weeks and hopefully by mid year he'll have a bunch in stock ready to ship...that's the goal.
VERY nice guy to talk to and from everything I've heard about their blocks, I would not hesitate to use one.

Sure seems like a good thing w/ KB being tough to deal with lately and Indy being, well, Indy.

Good luck with HP Performance,Dave is a great guy but we tried buying a halve dozen blocks from him but after a few years of casting holdups and machine work corrections as well as other issues we went on hold.We haven't heard anything from Dave for the past year.

He told me he had to change partners, get his equipment back, get everything set up again, etc. in the past couple years. Sounds like he has it rolling again now.

To the OP. Make sure you check that block for any breaches of the oil return holes to the water jackets. My block had this and I did not discover it until just before initial fire up!! I had to take the motor out of the car. Tear the entire block down and clean it all out and re-assemble it after I fixed it.

Just look down the oil return holes with a flashlight and make sure there are no holes entering from the sides. It is easier to spot from the bottom of the block. Looking up from where the oil return holes enter the oil pan area.

I fixed the problem by putting a tight fitting sleeve inside the oil return hole with some metal epoxy. I had my machine shop at work make the sleeve for me. So far so good.

Thank you 8sec and the rest on here.

I'll pass this info along to my friend and if he indeed gets some kind of refund, he can then give the business to HP or who ever else is in the market with some good honest products.
I also will suggest Bob George as a supplier to him or any others.

In hindsight, the one good thing I've found with some block families is that some are/have been exempt from hard core abuse depending on the chassis that they served in.
These engines such as the 318's-360's 383-400's-and some 440's served in station wagons, some trucks and most full size C-bodies.
To the contrary, the A-B and E bodies with 340's -360's- 383's, 440's and Hemis tend to be a crap shoot since they have probably ingested some level of abuse with the 340 and Hemi being the kings of pain themselves.

In this particular case, what I hate most is that with an honest 5+K down on a NEW block, it should not be useless junk and eclipse anything the old blocks endured. I totally understand the usual machining, clearances, decking, deburring, cleaning,etc. but none of that should come to a halt as a result of poor castings and or QC.

Rejects have been around since the beginning of mass manufacturing, but they should make the junk pile and not the in-stock pile to the public.

Heck, a sick Elephant from birth is truly an Elephant in the sick room.

You people that send KB deposits are playing with fire. That's all I'm going to say.

I talk with a builder not long ago .told me he wouldn't deal with hp because they have took people money and not delivered on blocks..but things could change. .

Regardless of quality, its a miracle FCA is even continuing to produce and sell iron hemi blocks. Knock on wood.

Sorry to hear of such problems effecting area 51

If anyone is interested we recently purchased a complete new hemi engine and it is now for sale.This engine has never been run and features all machine work completed"balanced and blueprinted" and assembled.We will disassemble it for buyers inspection and can offer it as a long or short block.If interested contact AJ@ BGR 412-216-4727
Also be carefull of any hemis on the internet,ebag/craplist and others,we have had many customers buy block/heads/cranks and misc parts that turn out to be total junk.
Thanks to Hemi Fred and others for your respectful comments.
