350 Small Block Starter

I wouldn't have a problem with welding on the block near the starter location with it in the truck.As long as your paying attention it is not a problem. Just lock the broken part in real good (after baking it in an oven or using a torch on it to get any oil/water out of the casting) Then heat the block area with a torch till it is warm, then weld the broken area with a high nickel rod and hit it a few times with a slag hammer to help relieve the stress. Once it is welded then use a tap to clean up the hole (if broken through the hole) or use a threadsert kit NOT a standard heli-coil to repair the holes threads. Then maybe put a strap steel brace up across the casting from the ear up to the next mounting hole.

Does the starter have the brace from the block to the front top of the starter motor like it came from the factory with? Go find one and your problem will go away. Brent

You're not welding the oil pan.

Use MIG process with the appropriate gas and electrode, and the heat is actually pretty localized.

:nods: listen to him- he knows the score.

I'm willing to bet if this block's been welded and has broken again, it was NOT welded properly.

We welded the top two links of a 4-link suspension to the cast iron on my buddy's Dana44 in the back of his TJ and it's held up with no damage at all. That rig is running a built 350, 700R4, Atlas transfer case, about 12" of lift, and a driver who thinks the throttle is an on/off switch .

Not so much as a crack in the welds. I'm SURE this takes a hell of a lot more beating than a starter bolt.

When welding cast, it's all in the preparation and preheat.

As I know perfectly well. I still don't think you can do it properly to an engine block full of oil with wires and shit hanging all around it.

Except to the whole "preheat thing" I'd feel safter welding the oil pan. You can boil water in a paper cup, but no water and no cup.
