The pics you posted are of known engineering exercises and have been written up in several mags over the years. I spoke to several of the engines in some of my earlier posts in this topic. These are the engines that Tom Nell was aware of too.
The TRUE HEMI 427 PONTIAC engine that was the engine in question (with the head bolts that go to the mains area) has still not been proven to be more than a engineer's dream. Tom V.

What is this 70's magazine everyone is referring to? Why can't some one post it?

They're talking about a 1970 issue of Hot Rod magazine; the front cover had a picture of a proposed 427ci, overhead cam Pontiac engine. It was pretty radical for the time. The article indicated it was only an engineering exercise and was not a running engine, but on the other hand you can't believe everything that was written in the car mags back then either, which is part of the big controversy here.

I'm on it Stuart, thank you.
If I win it, I'll post it as soon as I get it. |

If you want a copy of the magazine for yourself go ahead, but if all you're looking for is that specific article, I have a copy of the magazine myself and I could scan it in.

Both sounds good to me, I want to read it for myself and post it for others too. Be nice to have a copy of the magazine for my collection also.

Like I said before TRULY AN OUTSTANDING ENGINE DESIGN that never made it into production until Ford did it (in some respects) on the 4.6L Modular engine.
Similarities: The extra wide valve cover design. The cover for the spark plug wires. The front mounted oil pump, (Ford's is crank driven) The "easy to remove" front cover to get access to the cam drive. Fuel Injection (Mechanical on the Pontiac, EFI on the Ford). Long head bolts going well into the block. (Ford's are over 9" long) A very strong for its weight engine block. (A modular 4.6L aluminum block as run as fast as 6.70s in the quarter). Man, I wish Pontiac would have built that thing vs the Ford guys! Tom V.

A couple of pix from the 1970 Hot Rod article:
The rods look familiar...

I will try and look for a cut-away of the SOHC Ford 4.6L engine.
I firmly believe Ford copied the above engine in many ways. The picture shows the Ram Air V (Ford Tunnel Port) type connecting rod which was much later than the previous programs McKeller did. Tom V.

O-M-G ... Nice work there fiedlerh ! Now maybe a call to Knafel, or the driver of the 70 Tin Indian, or whoever bought car from Knafel, and see if any of them have recollection to these tunnel port hemi OHC heads and etc... maybe it became more than a designers dream mock up. Good Luck Dragn and Steve Groovy Sh!t |

The article talked about "electronic metered" injection on the Pontiac. The outboard headbolts on the Pontiac were 9/16" dia. by 14" long, tying EVERYTHING from the cam stands down to the main caps/girdle together! Tom- Do you know if any volume-production engine ever used die-cast blocks and heads, like this Pontiac intended to? Everybody- Has anyone ever heard anything of the present whereabouts of Huldi Aldikacti "father of the Fiero"? He was head of the Advance Design group when the article was written. How about Steve Malone, who was Pontiac's Chief Engineer at the time? Or Feature Editor Steve Kelly, author of the article? Edit 10/5/05: Tom, my question was answered by reading Ray Brock's Publisher's Memo in that same Oct '70 issue of Hot Rod. He called attention to the die-cast alloy block of the new Vega 4 cylinder.

Baron
That would be Arlen Vanke, but I have no way to contact him. I wouldn't even guess if he was the one that started the Goatfinder on the suggestion in the first place, although possible. I know these aren't what this thread is about, but I ran across them while looking and I think they are cool. M/T Hemi: |

I used to borrow a '53 VW, in which I think the parts were sand-cast, but not sure. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
