My guess is, when the guy who built it put it together, he just cranked the piss out of the outer bolt. Maybe there was already a stress crack or maybe just a flaw from the factory. Either way, I don't care. I just want to fix it now so I won't have to roll-start it once the engine is in.
Well then, oakie, doakie, mighty fine. The oil pan looked like the kind used with the Mexican made blocks; with the separate extra metal supports. You're still on the right track IMO. Post some pics when you have it back together, and offer an opinion on how it worked out for you. And again guys, let's see some pics of a mini-starter used to repair a broken boss. The other option, since you mentioned "rolling" it to start it, suggests it's a manual trans vehicle ( but there's a flexplate currently on your engine). So, use the early cast iron manual bellhousing, that uses the same starter, and you won't need the plate. Or, you could also go with an SFI scattershield; they also have the provisions for a bellhousing mount starter. You are aware you'll need a 168 tooth, 14" diameter flywheel or flexplate for any of these "repairs"; not 100% sure with the mini -starter however. IF it's for an auto trans, then it's the plate; or a cast iron Powerglide, or cast iron Hydramatic. Good luck. Butch/junior stocker.
