you have to come up with some solution that gives you a 130 tooth flywheel with a 5.9 balance weight and has the magnum crank trigger slots in it.....and notch whatever bellhousing youre using to clear the crank trigger
He isn't planning to run EFI, so he doesn't have to worry about the slots or notching the bell. Looks like the above link gives him a 130T flywheel option with the proper balance, so he should be good.
