Ok, I have an 81 W150, 4 speed, low mount starter (V8 position), and I believe (don't know for sure) I have an 11 inch clutch. Now, can I just get a flywheel for the earlier crank hub? If so, what application do I use? I was always of the opinion that the low starter mount setup uses a larger diameter flywheel - but I don't know why. I've read it somewhere, made the assumption... don't know.

I have an engine, but it's got the small hub on the crank, and I'd like to rebuild the shortblock and then swap it into my truck.

Any input helpful. Thanks.

Yes, you are looking for www.car-part.com for the "1963 Dodge Truck" D-100 with 225-6 4 speed... Any truck pre 1967 with the NP-235/435 4 speed will have your flywheel...sadly I had the bellhousing and flywheel out of a 1963 Dodge Truck 225/NP435 that would have fit your bill but I have sold both.

Good Hunting.

Have access to a lathe? You could turn a ring to center your flywheel on the early crank. If I had more free time I could make some up, but my friend with the lathe lives about 45 minutes from me.

Are you sure of this? Because there's more than one flywheel listed for my truck - based on clutch diameter. And no, I don't actually know what's in the truck now. And I thought the flywheels were different diameter for the starter location. Then again, I could be seriously confused here.

Trucks with the NP435 got the larger clutch and flywheel with the low mount starter. '67 and earlier have the smaller center hole in the flywheel.

Google helped me out, finally.

There's a "definitive" thread here somewhere that I could not find searching using the search here, but I stumbled onto it using google.

I appreciate everyone's input. Thanks!

I have located 2 wrecking yards with flywheels that are not too far away / not expensive. I've also found the transmission I want to change to, as well.
