Hello, This is my first post, so bear with me for all the "Forum" technicalities. Here is the scoop,

I have a 78 K-10 with a SM465 Tranny. I sold my 350, and have an old 6.2 diesel sitting in the Garage. I am trying to figure out what parts I need for rebuilding the 6.2. Got most of them, but the flywheel. The tranny I have is staying, it is the most dependable I think, and I just love the granny gear.

I still have my flywheel from the 350. it was brand new when I put it in (about 2 years ago) Looking at the mounting bolt patterns on the 6.2, it looks like this flywheel (from the 350) will fit up. Currently it is not balanced.

Will this flywheel work on a 6.2?

Should I balance it?
Should I just abandon all hope and suck it up and get a new or used one? (Flywheel, not FLEXPLATE, SM465 is a manual tranny)

I have read about 50 different conflicting thoughts, and was wondering what people on here thought.

P.s. I know I am going to have to use a high torque starter using this flywheel, but that is still cheaper than buying a new one.

will the diesel starter work with that flywheel? i say use it if it fits.

 

Look at the harmonic balancer on the 6.2 and see if it has a counterweight. If it does, the engine is probably externally balanced. I know the 400 gasser is externally balanced, not sure about diesels. If there is no counterweight, the flywheel is probably neutral balanced. Then you could run it no problem.

Not sure what you mean by counter weight exactly. Do you mean adjustable weights on the balancer? or do you mean counterweights as in metal machined out of the balancer. Mine has neither though.

Since it won't cost me anything, I think I am going to go ahead and get it balanced just to be safe. As for the diesel starter working, I have to pop the gear off of the Gasser starter, and press it on the diesel one for it to work, but that should be no biggie. Thanks for your insights, more are welcome too!

 

Inside the inner diameter of the harmonic balancer, there would be a counterweight. It looks like a crescent moon half circle chunk of metal. Balancers with the counterweight are externally balanced. If you look at a standard small block balancer, they have no counterweights because the engines are internally balanced. I guess if balance is free, do it anyway.

yes balance it if it fit cause the main reason a 6.2 blows up after adding horsepower to it is a bad harmonic balancer look into it and u can read all about it oh fyi a 6.5 turbo manifold bolts directly on a 6.2
