Quote: We like to use 100%Argon.There are a veriaty of rods if you preferr stick welding.What rod depends on the nickle content of the cast iron.What ever method you use peen each weld application as you weld.I don't suggest any novice take on this type of welding you can ruin parts very easy and create a unrepairable mess.
Good point! Would you know the nickel content of the current Mopar Performance 426 HEMI high nickel cast iron blocks
