Tech Question
Dan Kunkel, Black Hawk, SD, 86 dodge w100 318
Howdy,
I'm currently in the process of swapping a 360 from a '74 dodge truck for my current 318 in my '86. I'm having trouble finding a flywheel for that externally balanced 360. Several places have order a flywheel in for me just to have the wrong one show up. The last place listed an internally balanced flywheel for '78 and later 360's. What's the deal? Should I keep searching for the seemingly mysteriously balanced 360 flywheel or go with the interanlly balanced one that showed up in their computers?
Thanks a ton! Dan
Dan, all factory 360s are external balance. I can't explain the vagaries of the aftermarket - ask them why they are so screwed up!
But why not just drill the 360 balance holes in the 318 flywheel? This is what the factory did! This trick works fine on any and all ferrous-metal flywheels (i.e., steel or iron), and the specifications on the drawing are correct for all '71-92 360s.
The bad news? Expect to pay fairly big bucks for the drill bit. However, you could also do the math and remove the required mass - 19.79 in.-oz. - by using a pattern of smaller diameter holes.
So, you're welcome, although, as you can see, maybe not a ton.
