Individual cylinder heads

What heads and cylinders were used on that engine that had the individual cylinder heads?

Thank you, Tony

(2) Our 1963 Rampside (Sold 2014) and 1967 Ultravan #256 at Upper Canada Valley car show in 2009.
(UV256 aak Itchy Feet II - corvair power plant came out 2012 - plans with donor for a GM 3.8L FWD conversion, as a gas pusher, in the back of UV256)
(3 & 4) Are some of our 11 Corvair parts cars - to help keep our stuff on the road - hopefully as long as we live. ;-)
(5) Is one of our Wayne 100 boats (Corvair powered)
(6) Nov 14, 2012 Ultravans #362 and #512 arrived. We are getting closer to our goal of having an Ultravan museum.
We now own; UV248, UV256, UV362, UV512, and UV520 will hopefully be here July 2013.
(7) I saved Ultravan #231 from the scarp yard this year. It arrived May 9, 2013 and I plan to flip this one with a mid-engine Subaru power plant.

As far as I know, they were special prototype units and did not share anything with the production units.

I thought they may have come from an aircraft engine design.

From everything I have read, David is correct.
Pure GM engineering prototypes.

look back to the CORSA QUARTERLIES. Pics are included. A fellow here in Denver had four of the experimental engines from GM. He had gotten the pieces from Jim Hall after testing was done in Texas. He even had a set of the GM version of 3 IDA Webers. His car with that Weber engine was shown here at 1981 CORSA convention. Later all of the parts went to someone else and at least part of it is in the museum. New language now refers to the engines as 'modular'.

Phil, Those look cool. I like to have them. I wish someone knew who has them and that they would be willing to let them go for the right price.

Here's GM's largest "modular" engine

For those having a hard time counting plugs, that is 10 cylinders!

It was installed in to a 1962 Chevrolet with extended hood/fenders.

1962 WHAT???
A Tank?
That thing is huge!
Well, Looong anyway.
Those carbs look like the 2-barrel I used to have on my Chevy inline-6!
Must have been a "Full-sized" '62 Chevy, it has a power-steering pump.

I recall reading from Dave Newell's articles in COMMUNIQUE that the 10 cyl installed in front of Chev was test vehicle for upcoming OLDS Toronado pakg.

According to the R&D guy that showed up to one of our meetings had pictures of 8, 10 and 12 cyl engines! He also said that they were intended for the Impala but they could never get the engine to cool.

The modular engine has one piece head, barrel and oil drain. No pushrod tubes. From what I understand it had cooling problems. Not enough fin area

The two engines that Ron had in his car had no cooling issues. Ron used the car daily.

The cooling problems, suggested above, occured when the engine output was *considerably* above 140 hp. This was during GM dyno testing the emgine that would solve the oil leaks at the pushrod tubes (because they were integral with the head+barrel sub assy), had no head gasket, had higher CR, aircraft-type ports for high flow. That engine was aimed at Corvair's attack on the pony car -led hp war of the 1960s.

Airflow on the underside of the head and cylinders was almost completely blocked by the pushrod / oil return passage. The production Corvair has the tins to direct air to the underside of the barrels and air passages between the rocker box and the top of the combustion chamber.

If only they had added a water jacket, like Porsche did later, it would have been an amazing engine. Modular to fit-up to many cars. I guess the small block took the win. Imagine what front ends would have looked like in the 60's with a low profile engine like that! Aerodynamics would have entered much sooner.

I wonder if they could have "finned" the drain area to improve cooling.
