New Hemi aluminum blocks

[C Body Bob]

Veteran drag racer Alan Johnson (Top Fuel) manufactures his own Hemi race blocks. He uses them in Top Fuel (nitro) & Pro Funny car. As well as sells them to other teams & to Top Alcohol cars. He starts off with a chunk of aluminum & machines it down to a 426 Hemi style block.

He posted this on Facebook & made a joke about how to turn 720 pounds of aluminum into 500 pounds of aluminum shavings

Better weight distribution in a Cbody hmmm...

For sure. However I don't think the AJPE blocks are water jacketed. The World & Indy blocks are though. They ain't cheap

Won't have to lay out for a Valley Pan anyway . . .

Amazing what a CNC machine can do these days!

A bare 440 block weighs about 240 lbs so you are saving about 60lbs, that you can save in easier ways, inlet manifold, headers, aluminum heads, aluminum water pump and housing. That will save more than 60lbs for a fraction of the cost. Its nice to dream, but the practicality isnt there.

Thats where my brain was going as I was reading......

We can thank the cold war for driving much of the CNC technology that we have today. After we bankrupted the Soviet Union, the United States was left with a great deal of CNC machining capacity, that had formerly been used for the manufature of military equipment. Looking to fill this capacity, many CNC centers' capacity was filled by turning to aftermarket hot rod parts manufacturing.

These block are WAY WAY WAY stronger than any iron block. Raised cam. Bigger cam journals with rollerized oiling provisions. Wider crank saddles for stroke & oiling considerations. Iron cracks under stress. Aluminum bends & survives the round. Much easier to repair these blocks when damaged. Many after a few races are sold to sportsman racers even after being windowed.

And all Don Garlits ever used were "seasoned" 392 Hemis. . .

Stan Garlits used KB's & the JP1's. He even endorsed the JP1. I imagin he used the Donavan at one time too. It was an aluminum 392 with 417 inches

I believe this is the Ford 426/500 inch Gen II Hemi block. Yes Ford. Back when they where sponsoring John Focre they had their own blocks cast & made some minor changes to them. Basically so they could now say it was a Ford design. They called it the BOSS 500 engine. They basically copied the KB block

Here is one all dressed & ready to race

 

[C Body Bob]

This is a stock factory style RB main cap & a KB alumninun cap. The KB cap is stronger, wider, taller & thicker. All of this has its reason. And it's cross bolted too

 

[C Body Bob]

Here is a repaired KB block. The well funded teams will not use this. It will get sold to another racer
