Re: small block mopar, road of hemi ?
With the benefits of the HIP. process, I shall attempt to "shrink" a hemi head onto the LA and Magnum sbm. Don't order the lobotamy-jus-yet. roverman.

Re: small block mopar, road of un-spoken
Art, are you saying that you plan to take a hemi head, heat it to 975*F and pressurize it with 15,000psi of argon in the hopes of shrinking it down to the sbm bore centers? (where do you find 15,000psi argon?)
Now THAT is some radical thinking. JB |

Re: small block mopar, road of un-spoken
Hey Jim, I think Art already tried shrinking the head with unexpected results.
Just kidding Art. If something like that would work, oh mamma couldn't we have some fun! Rather than mess around Art, I have a 511ci 780hp bbm in my Jensen Interceptor. If we dropped it from around 8 feet into the healey it just might fit. Cheers Fred |

Re: small block mopar, road of un-spoken
Jim, Let's not blow this out of proportion...It's only 970F. Company is called "Kittyhawk,"(Wright Bros')? Garden Grove,Ca.Using retired gun barrels from battle ships(pretty strong).Fred, no Hemi in a Healey, it's for the noisy Cuda'. My Healey wants' to carve some "corners" against your LandYaught , on the inside, a good idea. lol., roverman.

Re: small block mopar, road of un-spoken
Jim, thanks for the suggestion. Spotted a bare set of "Arias", asking $ 485. "IF", this works, I think we know what,series of motors, would be next project ? roverman.

Re: small block mopar, road of squeezen
Jim and clan, plan is to "squeeze" a junk, sbc alum. head, to make it-you guessed - a "shrunken head". lol. for more hp. roverman.

Re: small block mopar, road of un-spoken
So I'm guessing they pressurize the chunk of gun barrel (breach with welded plug in short barrel section) with about 2500 psi argon, chuck it in the oven and let the heat generate the rest of the pressure from expansion of the gas?
Are you doing anything to seal the pores of the aluminum? Copper plating maybe? Make a "copperhead" engine! JB |

Re: small block mopar, road of un-spoken
No copper-too heavy, lol. Maybe more correct term is the inert gas,(sucks-out) the porosity? Don't know/care, just take out the air(pores). A billet head with coollant passages. How "cool" is that " roverman.

Re: small block mopar, road of un-spoken
Okay, this is too damn funny.
Whatever happened with this 'shrunken head' idea, Art? |

Re: small block mopar, road of un-spoken
I'd love to see the results, all you really need is a gun breech big enough to take the bare head, an oven big enough to hold the breech which can get up to 1000° F, and a fresh bottle of argon. Seems easy enough. The cast aluminum isn't fully dense so there are internal voids evenly distributed. That temperature should have the aluminum in a near-plastic state. By the time you shrank it it would be roughly equivalent to billet material in terms of density and strength.
The reason I suggested the copper plating was to seal the voids that were close to the surface to make the shrinking more uniform. Just a few thousandths would do that, and it could be electro-chemically stripped off afterwards. Any competent plating shop could handle that. (Though wouldn't it look cool to have copper plated heads?) Jim |

Re: small block mopar, road of un-spoken
Like soo many of my "lightbulbs", I don't seem to posses enough Hz, to light all of them. From 7/2010 till now, once you observe the marvelous Gen III hemi heads/engine,(think of it as a sbm on steroids), no need to search further for a better sbm head. IF I could "only" shrink it to fit the RV8... Onward, roverman.

Re: small block mopar, road of un-spoken

I don't even care if the head bolts and water passages are close to lining up. The aluminum head shrinking thing ( are you part South American aboriginal? [en.wikipedia.org] ) is what I'm curious about. Now you've got me wondering how you would control the shrink. Is it primarily time under pressure or absolute pressure that would control the compression amount? How much psi would you have to hit it with? I wonder if they ever took any aluminum objects into the Marianas Trench? That would be a proof of concept. |

Re: small block mopar, road of un-spoken
Seems like I remember the preliminary research work was by Dr. Timothy Leary back in late 50"s or early 60's. Some kind of CHEMICAL caused reality to become one's worst nightmare occasionally, but enabled mind expanding fantasies. :-)

Re: small block mopar, road of un-spoken
"Marianas Trench", has much pressure-indeed, but how do you maintain 975 F ? I suspect shrinkage will stop when all of the porosity is gone, as in density of billet. Sometimes, less IS more... roverman.

Re: small block mopar, road of un-spoken
but how do you maintain 975 F ?
That's easy. Encase the head in a uranium / inert matrix. As pressure increases with depth and forces the U-238 molecules closer together you gain heat. Where's a "hammer to the head" smiley when I need one. |

Re: small block mopar, road of un-spoken
gno,gno gno, in the alternate universe, densities, or the lack thereof, become reversed. Of course you'll need a self reversing/propelling worm hole ! Got one ?
