I just scored a V6 out of a 1985 Buick that only had 14K miles on it for $250.
Now I have to decide which Jeep to put it in.

Check the timing gears before you run it too much. The original plastic coated aluminum gears did not hold up well and it would be a shame to wipe out the valve train.

A good point. I plan to install a different cam anyway so will have a new gear set.
Thing I am scratching my head over is the plumbing for the Rochester Dual Jet carburetor, which has more fittings than I know what to do with I know what to do with the excess of vacuum fittings, but there is a hose barb fitting near the top of the carburetor which I assume is for the fuel return line, not sure what to do with that since my fuel tank does not have a return line fitting.

One of the ports is the vacuum advance for the distributor. I don’t recall there being a fuel return line for the carb, that takes place at the pump.

If I remember, that upper vent is simply plumbed to the air cleaner so it gets fitered air.

Not exactly TO the air cleaner, but it is a source of clean air for the hot-air choke. Look inside the air horn, you can see the end of that tube, if it's the one I'm thinking of. BW

A lot of peole don't know the difference between a 2G and a 2GC. I think you are correct, it would be a 2GC.

If you have one of these later V6's, is it a good idea to use a heavier flywheel like the 225?

The 49 pound flywheel helps even out odd fire impulse and promotes low rpm torque via inertia. Edited by oldtime - 16 Mar. 2021 at 2:18pm |

I don't remember if the even fire engines are internally or externally balanced, so if you're contemplating using a 225 flywheel you may need to do more research. But a heavy flywheel would be a good thing.

The ideal situation is a rotating assembly balanced with the flywheel. Not always practical. Used on an even fire the dauntless flywheel should be neutral balanced at a minimum. Generally you can " get away with it" due to the low rpm usage.

My 3B V6 has a manual choke, it was a bit of time to learn about how to use it. Strange, on the coldest of mornings, It would start so I could jumpstart my work van. The 'Mando has a 2GC. It took a bit of tweaking to get it working well.

If you are not doing a full rebuild with the crank out, but swapping flywheels. you should be able to take the original flywheel or flexplate from the engine to the balance shop to match the new one.
