Finally, life has allowed me to get back to this project. Being temporarily unemployed has given me the time at least.

Today we got the flat 6 out and worked on comparing depths and dimensions for the flex plate/ converter. I have a MidEnginering adapter to use. The way my rough measurements read, I will have to have a spacer made up to move the flexplate about 1 inch and will have it machined to accept the PG converter hub. I'm thinking that this adapter bell is actually for a stick but if the machine work is right it should work.
I need to get the camera fired up to log the proceedings.

lostbooger, Have you had a chance to drive you 4.3 much more yet?

The adapter bell housing does not have openings for transmission cooling like the stock Corvair one. I added the trans cooler lines to my PG, like forward control, and I am using the trans cooler in the radiator. Also tapped the gas tank for a return line as my 86 4.3 has a return line on the fuel pump.

I have found where to drill and tap for the FC cooler fittings but I have yet to find the specific internal changes to ensure that the oil flows through the cooler.

Did the FC have a bypass valve in the bump housing? I have been looking for an illustration of that valve.

With out an internal change in the flow, the cooler wouldn't have full oil flow.

I'm going to get the camera fired up as well.

Thanks for the knowledge guys

Made some mock up progress today.
Lets see if I can get the pictures to work.

I will be looking for a shorter intake, shortening the pan and seeing if I can find some shorty headers.
I will be talking to my machinist about building the adapter for the Corvair flexplate to the 4.3 crank.

I think only aftermarket aluminum manifolds are shorter. I am using a holley manifold.
You might be able to use the tbi manifold by milling the tbi pad down and using a carb adapter.

I'm not having a lot of luck on the intake for the early 4.3. I can find a few for the later vortec heads. One thing I'm looking at is the marine intakes, we're not looking for a large performance gain, just hopping to get it under the lid!

What are you using for the motor mount? Also, did you line up the crankshaft with a mark on the rear bulkhead so you will retain the correct alignment, left-right and up-down? Which water pump will you be using? The factory tubular manifolds look like they are pretty efficient. If you want to look for other tubular headers, there are some on E-bay. look for S10 medium length or shorties. I think there is enough meat on the Corvair Flexplate to drill the V6 pattern same as the V8. What year is the crankshaft? 85-back or 86 up.

Craig replies:
I have a complete Mercruiser marine 4.3 V6 with a factory 4bbl intake and factory Edelbrock/Weber carburetor.

I don't want to sell the manifold and carb because I plan to sell the entire engine in the spring. But, if you want, I can measure from the top of the valve cover to the carburetor flange so you can know if it's any shorter than what you have.

I am old and very slow. LOL. I am getting close to starting it, in the car, and see what problems I have. I have never posted pictures, maybe I need to find out how to do that. I have 65 Monza that has about 69000 original miles and the 66 Monza that it not original with 4.3. The 65 had been in dark storage for almost 40 years when I bought it.

The intake manifold, the only after market one, is the Edelbrock number 2111 is for the non vorteck 4.3.

4.3 with aluminum heads ,headers and aluminum intake would be a great power plant.Lots of power but drivetrain would stay intact smiling smiley

I keep telling myself that Mel - I have an all aluminum 4.3, waiting to build. But I am so damn lazy.

Seth, we are building a mount similar to the factory one. I have cardboard mock ups made, need to get the steel bent for it.
I built a jig for the centerline location.
I am looking at different headers, I would like them to dump closer to the bell, like the "passenger side", drivers side now.
We are running an 85 engine.
There needs to be a spacer to bring the vair flex plate back to the converter and locate the pilot for it as well. I think I have the measurements and just need to talk to the machine shop to get it built. It will bolt to the crank and have the vair bolt pattern and pilot dimensions on the back.


Mel, I'd just toss some chrome on it and leave the lid at home if it were mine!

Craig, If you could measure that would be much appreciated! I have found a Mercruiser 2246 intake on the Ebay for a fair price. I',m trying to find the height of it before I bid.

Jerry, I'm hoping that the Mercruiser intake is a bit shorter that one.
