Not really so much a tip other than find someone experienced in welding cast iron. We have a local welder here who does all sorts, aluminum, cast iron etc. He did one for us at the dealerhip years ago and it's still going strong.

Laugh if you want about JB weld...But if you have a broken part that needs fixin, this stuff works...I once took out a tranny on my 84 chev truck, in my old driveway, broke a chunk off the bell housing cuz I left one bolt at the top loose (insted of one on each side)...anyway...I used JB weld to stick the 2" chunk that broke off back on and I drove it for years after that and it held like new.....Anyone else with a JB weld story?

we use it on Jimmy/ Blazer oil pans when they get "wacked in the front", the front axle moves back and cracks the pan... We clean it up, and put J-B on it and let it sit overnight They don't leak lol

I have had good performance from marine-tek - a similar product. Bonds tight and holds forever.

We stocked it in industrial size at the railway for repairs to the engine blocks on the deisels. Works good on cracks but not sure on how it would hold when bolt pressure is applied to it. GIve it a try, your not out much if it does not hold.

I think I would put in a stud, weld in the missing piece and use a nut instead of a bolt.
For the stud, I would use an original starter bolt with the head cut off to retain the proper unique features the starter bolt has. I would saw off the head and weld a threaded stud to it to run the nut onto.

I used JB Weld on a snowblower I was given in which it blew up and punched a hole in the block. Fixed it up, replaced some of the inner guts and she's still chuggin' away 13 years later and not missin' a lick nor is there any oil leaks or sign of the repair breaking down. It's a really excellent product that holds up well......or would that be.....holds up weld? Hmmmm.......

I have heard JB is excellent for stuff like block repairs. However, for the starter bolt where it is threaded and has to adhere to the side of an existing iron piece, I would be less confident.

I think your idea Carl is the way to go, the stud is a good idea.
