PONTIAC ENGINE MOCK-UP BLOCK
 

Is there any source for one of those fiberglass or plastic engine mock-up, or display models?
Kinda big for a 3D printer?
Maybe someone has any leads?

Haven't heard of any......
 

Guy we know who've done mock-ups just used either a 'windowed' block or something they have laying around.

Good luck!

I have a Pontiac 400 block that I had a friend "Epoxy UP" the Lifter Bores and I made
aluminum plugs for the Camshaft bores on the front and back of the block.

The oil dipstick location was used to get the crankcase suction pressure, and the
Pan had a stub section (3" diameter) where I could hook up my vacuum source.

The vacuum source was 8 Ametec 115923 Vacuum Motors.

I worked with Ricky Hunt on a similar flow bench (for the Butlers) before they purchased a Superflow
Bench for their shop. I did this years ago and it was written up in a couple of Jim Butler's early Catalogs.

So my block is used for multiple tasks: Flowbench, Mock-up engine for intake and exhaust fitment (turbo)
and Belt drive Supercharger Systems (Vortech Supercharger).

Well worth the effort.

mostly something we can display an intake or valve covers, and just pick up and move. I know there's a million Chevy and Ford plastic blocks, but surprisingly no Pontiac.

Figure the time frame when Pontiac KILLED the Traditional Pontiac Engine.
Not very many car things were made from Plastic in those days.

Doesn't some isn't doing one now or in the past 20 years...

Have you considered taking an oxy/acetylene torch to a 557 block? :Ithink:

The factory made it lighter already, just take things a little (or a lot)
further. Which is the lightest casting, 350 or 400? Doubt it'll ever
be considered a lightweight, but it certainly would make it more
manageable.

And if it's for a display, talk to coupeute about his engine cradles? :noidea:

If youre just needing it for external dimensions, just take a BFH and knock the main saddles out of it, that will remove a bunch of weight.

I have been using the same mock up block for the last 20 years.

Just a garden variety 350 with yucky cylinder walls. I toss on whatever set of heads are closest that day.
