Magnum Swap Flywheel

[Haney]

What is the cheapest option for a 5.9 Magnum balance 130T 10.5" Flywheel. I do not have a neutral balance FW so I have nothing to add a weight to. Starting from scratch.

Thanks,

Depends if you want to run the FI or not.
If you are, then it's aftermarket only, it needs to have the pickups for the crank sensor.

If you're not running the factory EFI, then I think any neutral balance flywheel (common=cheap) would suffice, as long as you use the 5.9 mag weight (aftermarket) or have it rebalanced to magnum specs.

I am running a carb. So I do not need the crank sensor

Can't vouch for it, haven't personally used it, but here you go

I'm sure there are others. Smart shopping can snag you a good used 318 or early 340 flywheel on the cheap (relatively speaking).
Make sure you address the pilot bearing/crank issue before you put it together.
