Pretty cool they got it running and it makes the power Oldsmobile said it made, go figure. The great what if is now a one off reality!

 

So cool. To see it actually put into a car and running is awesome.

 

Now, start building upgrade kits I'll be the first buyer!

 

For an existing 455? Sadly, that is not possible because even the block is different. Then you also have the same cam issues to deal with that were never refined out.

 

Sorry but that's really a weak article. The original article published in the May 1971 issue of Hot Rod was far more detailed and informative, and was based on interviews with the engineers who actually worked on the project, not an internet search done half a century after the fact.

 

I wonder if they laser scanned it. Whittling a billet version on a Haas would be bada$$, but cost a small fortune.

 

I'm sure this is a business expense for advertising.

 

They would need an original or a molded plastic model to laser scan. Chances are it was some 3D computer drafting program that was loaded on a 3 axis CNC machine with 5 axis capability. Finding a billet large enough could be another project.
That block would cost more than a few sets of Peyton Hunt heads.

 

 

Inline had a new head cast. My understanding is it took several tries to get a useable head.
