HelloCustomerand welcome to just answer.

If the threads are pulled/stripped out from the block then you can drill the block and use some "Timeserts" or "Helicoil" for the repair.
Unfortunately if the block is actually broken/cracked the only way to fix it is with a replacement block. It is cas iron and can't be welded.

we r in cleveland ohio cleveland certifed auto weld can weld cast block with 100% gurantee but engine has to be removed from vehicle (block corner broken off) looking for simpler answer maybee some kind of repair kit being a common problem

Braking the corner off is the simple stuff, repairing it is not, I think you will have to pull the motor.
never heard of anybody fixing this with any repair kit. you will have to improvise.

I have fixed some of these by drilling and tapping further up in the block, then cutting/grinding out the block around the broken corner so that it is flush/square and installing a longer bolt with a spacer block.

Best regards
