Found this pic in an article. Writer thought the engine might have had a 180° crank.

Thanks for the Great Naturally Aspirated M/T Pontiac picture.

It would be very easy to do a DUAL Blow-Thru Carb Bonnet set-up (with the AFBs) like the Paxton Supercharged engines had). A guy in Kansas has a "Pontiac Paxton Supercharger" set-up for a PONTIAC Engine on the shelf.

What a cool Street Rod intake set-up that would be.

I wouldn't be surprised if it was a 180-degree crankshaft in that engine. It would run like two slant fours. I always wondered if the M/T crossram was developed to be used with a flat crank, it would probably work well in that application. Thompson was very much an engine scientist and I will bet that idea crossed his very fertile mind.

Interesting water pump,looks like a Sherwood or Jabsco marine pump.You see there how to plumb the water to each head.Also the chain sprocket on the crank is a wonder?Damn I wish Fritz was still with us.Tom

All the engines ever used in the streamliner (both N/A and blown) were iron blocks.
As for the "-2", the whole D-number was assigned and stamped by PMD.
Why do you say "1960"? The first mention by journalists of the initial Harvey Aluminum castings was during 1962.

Why on Earth would they cast a performance ali block-but leave the valley area open?

Agree, what were they thinking?

Joey Fair at Mayfair Automotive in the early 60s (not sure if I have the business name right), was adding the turn-buckle mod to the old mechanical FI intake manifolds (as the extra strength from a factory 4 barrel style intake was no longer there) to help in the weak Pontiac stock valley area from spreading and cracking in the area with race camshafts and large stroke cheater engines. Good question taff2

Jack,I think the blocks were done pre 1961 as everyone except for one has had the 55-60 bellhousing pattern.The complete alu engine I had although it had the 61 pattern the heads had the 55-60 water pattern and as I remember had 1.88 intake.Maybe the word did not get out to the press till 62 I think they were much earlyer.The hemi blocks I have are the first with somekind of performance built into them with the joined lifter bores.Tom

The originals were NOT performance blocks. They were merely aluminum copies of the '60 389 block, for PMD to evaluate possibly substituting plated bores for iron liners. The first one I bought from Mickey still had remnants of plating on the bores, and witness marks of thermocouples being used on the decks.

Not pre 1961. Pontiac waited until they were done casting 1960 blocks, so they could loan the sand-cast patterns to Harvey Aluminum Company (per phone conversations with Mickey and Fritz).

Giving credit where credit is due, Mickey Thompson just copied the "Outside Intake Port"
design that BRUCE CROWER first came up with for a Indy Car Engine.
Bruce cast up about 18 sets of heads (based on a Chevy engine design) and the Indy Rule
Makers killed that super high flowing head design.

So Bruce Crower gets the credit for the design and there is lots of info out there to back that statement up.

REST IN PEACE Mr Crower, (passed in 2019). Thanks for the memories at Bonneville in 2001 when I first
met you there and we talked for hours.

Those were a Version of the Ford 300 (4.9L) 6 cylinder heads made in Australia.
Actually there were quite a few versions of those aluminum 6 cylinder heads designed and made by the Guys Down Under.

I did the Boosting (Twin Turbos) for the America Ford 300 6 cylinder Prototype Heads that Ford never offered in the USA.
Nino & Gino Novelli did the calibration work and engine fabrication work on the engine.

Came across this today. Not a Pontiac but a Buick nailhead with the intake and exhaust ports swapped and a very unique induction setup.

The Potvin Crank Driven superchargers were always one of my favorite boosting units in the old days.
Street Rods especially. click on pic as usual.

Probably one of the best street rod units as you give up NO front visibility of other vehicles around you.
