Flywheel

How do you tell a 340 standard flywheel from a 360 flywheel. Not a flex plate but a FLYWHEEL

By whether it has the balancing holes drilled in the back side or engine side of the flywheel, not the clutch side. There should be 3 holes drilled in it if it is for a 360 otherwise all the rest of the small blocks do not use a flywheel with those holes. They do not go all the way thru so it needs to be off the engine to tell. The holes are located like in the picture on this web page, remeber this is if it IS a 360 flywheel, otherwise it dosn't have them. flywheel balancing diagram

Thanks

I will dig it out of the parts bin and take a look,going to take it to have it surfaced tomorow if it is the correct flywheel. Getting ready to convert the car back to 4 speed and want to make sure I use the correct parts! :salute:

Thanks

Cast crank 340's were externally balanced so their flywheels will be offset weighted similar to the 360's

The 360 flywheel had three holes 1-13/16 x .66 deep. The Direct Connection Manuel says it is a one year only (1974) flywheel in a passenger car. The 340 cast crank flywheel has one 33/64 x .84 deep hole. I have an 11" flywheel out of an '86 Dodge truck that has no holes. A friend of mine looked at it and said it is definately a 360 flywheel. He told me the difference and I still don't see it.

Pictured is an 11" 360 flywheel for a truck, which is representative of the 10-1/2" version.
The 10-1/2" 360 flywheel was also available in 1971 'C' bodies with a 3 speed column shift 360.
Yes, I have seen ONE such car.

The 340 cast crank flywheel has much smaller holes in the same positions, yet further out towards the edge, and are fairly hard to identify as originals.
