What is this

Post by vectorit »

Just looking for input on what I'm looking at here.
It came out of a 1963 Monza convertible to be rebuilt, but since the work was done the engine has not made it's way back to the car yet.

Thoughts?

Not entirely new to vairs, but am new to the 1st gen vair.
Working on a deal to get a 1963 Monza convertible, and trying to figure out what it has for an engine.
Looks like a 140, with a turbo system.
Can't tell if it's original to the car, but it is all new but has been sitting for a couple years.
So, here I am. Frantically researching what this could be.
Turbocharged Corvair.jpg
This is not your average, run-of-the-mill, Corvair grocery getter. I was able to figure out a little about the intercooler but I don't know enough to identify the custom turbocharger or fuel system. It is fitted with an alternator (1965-69), but does not have a harmonic balancer — just a standard early design (1960-63) crankshaft pulley. Hard to know what the base engine was. The engine serial number and head casting numbers might help a little, but everything has been heavily customized. But it does have a magnesium cooling fan from a 1964 or later engine.. It does not appear to have 140 hp cylinder heads, but some custom secondary intake manifold modifications. No way to tell how customized the internal engine components are, or its state of tune (racing only, street, etc.) If it can be made to run again, it may take significant research, investment, time, and experimentation if there is no documentation or contact with the original builder. :dontknow:

Thanks Brad for the reply.
I realize my pictures are not the best, and the info is lacking right now.
I was pressed for time, and the owner had just begun to offer everything to me for sale.
So I was just trying to take everything in mentally, and look at the condition of the car then to the mechanical parts.
Here are 2 more pictures of the engine, maybe they are helpful maybe not.

Appreciate the input.

Not mentioned so far... the fuel rail visible above the valve cover. This engine was fuel injected! Is the rest of the EFI system still in the car? If it's there and you post a photo, maybe someone can identify it too. Very cool custom engine. I wonder if Ray Sedman (American Pi) was involved...

Pretty Injenious turbo setup but as bbodie said who knows what the actual engine is. I do see 3 separate fuel injectors. It looks like a t3 turbo from the hot side. Spearco is great stuff.

Cylinder Head Casting Number.jpg
The cylinder head casting number in your photograph (shown above), 3856759 is from a small valve 110 hp 1965 engine with 164 cubic inches of displacement. (The intake and exhaust valves on the 110 hp head are the same size as those used on the turbocharged Corvair engines). The original compression ratio with these heads was 9:1. By comparison, the standard turbocharged heads used with Corvairs always had a compression ratio of 8:1. Each head on your engine originally only had a mounting pad for a single carburetor on the intake manifold. The distributor on your engine appears to be stock, with an original points and condenser arrangement. There is no way to tell what the initial timing setting is from the photograph, or whether or not the centrifugal advance has been modified.

If the rest of the base engine matches the cylinder head casting number, the engine itself would have a long stroke 164 cubic inch crankshaft. To support an exotic turbocharged installation such as that shown on your engine, the bottom end may have been beefed up somewhat with modifications to the connecting rods and possibly forged pistons. The original camshaft in this engine was the same for both the 110 hp and 140 hp engines. The actual camshaft grind that you will find in this engine and the compression ratio may have been modified. The bell housing is that of the design used for a Powerglide two speed automatic transmission. That transmission never worked well in conjunction with a turbocharged engine, and General Motors never produced any turbocharged Corvair engines that were mated with a Powerglide transmission. It appears that the crankshaft oil seal on the bell housing is missing.

It appears that the bell housing had developed a crack at one time, because it looks like it has been welded to repair the crack. The valve covers, push rod tubes and cylinder barrels were all painted, apparently to customize their appearance. Somebody spent a lot of money and time modifying this engine for high-performance. The exotic nature of the engine may indicate that it was built for dragracing or some form of competition. It is unlikely that this engine was ever intended for use on the street. If you are looking for a Corvair that will be intended for street use, replacing this engine may be necessary. It may be possible to sell this engine on eBay to someone who would enjoy tinkering with its exotic capabilities.

I managed to find one other Corvair with pictures on the Internet that included a Spearco intercooler…

Jonathan's intercooler in that picture, is actually a Subaru intercooler. I know because it is in my attic along with all the plumbing, turbo, carbs etc. I bought it off him 5-6 years ago. It will be going on my 63 in the next year.
