Just make sure who ever welds it does a pre-heat and post heat if you're going with a 70 series wire,it'll make all the difference in the world.
You should be fine,you are welding steel to steel,not cast iron to steel as most think.
As i've already said,most like to use the high nickel filler for the fact no one knows the exact chemical composition and process it was made of...but..i've seen many 8.8's welded with 70 series filler on dirt tracks and drags strips and most of them held up great,the one's i've seen fail were the ones that were not pre and post heated.
Only heat to around 400-450 at most,any higher is chancing damage to the composition of the cast steel
I always use a high nickel filler,but the filler metal is much higher in price.
Use fluxcore,it is a stronger weld than MIG,general rule of thumb is any weld that takes longer to cool is stronger and less brittle,MIG cools very fast since it has no flux.
