Looks kinda chevy-ish to me!

Yeah, but the valves are huge (stock 426 Hemi size) and of course the design is probably light-years ahead. I bet that thing has more power potential (especially naturally aspirated) than the original 2g Hemi. In the description he even says it's set up as a street engine but makes over 550 HP! If I had the cash I'd go out to San Diego myself and buy it and drop it in a nice B-body.
 
2nd time it's been on ebay.

Mopar Muscle did a write up on them a while ago. If I remember right it was designed to go into the A-bodies, there were 2 built, one went to Landy to "borrow", ma mopar forgot about it then remembered and wanted it back Landy kinda conned mopar out of it and got it. He kept it in his museum all these years until he sold it to John Arruzza. I can't remember what happened to the other one.

I have the issue I just can't remember what date it was.

Here is another article on it.

Just remembered one of them ended up in a notchback cuda, did a search and found this...

from http://www.carlisleevents.com/ce/contact/pressview.asp?PRDetailkey=10

"12 Tom Hoover 1CGodfather of the legendary Chrysler HEMI engine. Hoover was also involved in designing the next generation of the 426 hemi engine. He built the famous ball stud hemi motor that disappeared for over 20 years. John Arruzza discovered the motor and rebuilt it. John also purchased Tom1&s 1&69 440 Barracuda and installed the ball stud motor in the vehicle. Be there as Tom is reunited with his ball stud hemi motor and his original Barracuda."


One of the mopar mags did a write up on the cuda with the motor in it.


Here is some more stuff on it.

It was a prototype of what the next generation of HEMI would have been. The goal was a lower maintainence engine, that did not need the frequent lash adjustments that the solid lifter design needed. This would have adjusted much like a small block chevy, but rather it would have been torqued down, and DONE.
 
Thats really cool. I guess the times dictated that the project get dropped ( gas crunch ). Can you imagine what chrysler could have done with that?!!!!!

Too bad.

It also had much shallower/smaller chambers and the valves weren't located in a perfect cross-flow arrangement. This saved space, reduced weight, and simplified the valvetrain setup, as well as improved combustion dynamics (especially on higher-compression N/A applications) by not requiring a huge piston dome to keep the compression up.
 
If I remember correctly, Chrysler had a lot of wear issues with too much friction in the valve train. Arruzza had to use modern coatings on many parts to get them to live. It was more than just gas costs that killed the project.
 
The biggest difference was not the type of rocker and how they are adjusted, it was the way the engine filled the cylinders. The valve angles allowed lighter pistons and also helped.
They would have probably been better off with a rocker set up that was more like Magnum rocker gear on this head.
 
Look at the heads, rockers, and intakes folks. Those are TWO DIFFERENT designs. The one on ebay has a "standard" Hemi intake setup (check the bolt holes) while the orange motor has a "standard" RB type intake setup on it. Also, the rockers are completely different between the two. The orange motor also has pushrod guide plates in it.
 
Howdy gang. The ball stud hemi engine on ebay right now is mine so i thought i would clear up a few things. The orange engine someone has pictured above is the one that Arruzza installed in Hoovers 69 barracuda and sold. I puchased mine as a large parts pile from arruzza a couple years ago. it was missing some things and we had to improvise. I did not have rockers so we sorted out using modern roller rockers. I do have guide plates, just a different type we had to make. You can see them in the pics if you look close. the intake shown in my ebay pics is a stage 5 426 hemi type that is just sitting on the engine. it will need to be modified quite a bit to use but i think it would be better than a single lowrise thermoquad piece. The heads are the same between the two but mine have been cleaned up and hardened exhaust seats installed. I built this thing to be driven and used, if it does not sell i will eventually put it in something and drive it around. I had it on ebay once before, when it was unassembled. Feel free to ask more questions!

is your a279 the last of its kind because some people say that there might be one more floating around. is this true?
 
just a bigblockchevy/385series bigblock or cleveland type motor in my eyes, its not like the engineers invented the wheel or something like that, but still a very cool motor and alitle sad it was not developed further

Tom Hoover stated the A279 would have made for an excellent high performance race engine due to the light weight, excellent breathing, excellent combustion chamber design and swirl fill ports on all 8 cylinders that fill the cylinders very nicely by the nature of their design. Big block Chevy engines have only 4 swirl fill cylinders and 4 back fill cylinders thus not giving the engine an equality from cylinder to cylinder. Same problem for most wedge &#8211;style engines including, sadly, Chrysler&#8217;s own 440 and Max Wedge-style engines. Even the small block Chevy has this problem.




That's no BBC copy....maybe check your eyes???
 
If anything it and the Boss 429 are comparable, which makes sense, the Boss 429 was starting to contend with the Hemi in NASCAR. The Gas crunch, Emissions, etc killed them all.

Oh, and never compare a 385 Ford to a big block Chevy.

http://www.highflowdynamics.com/ and click the "Advantages of Ford Over Chevy" and have a good read on "era" specific blocks. Just a little FYI for any engine melvins....
