I was taking this 440 apart to check it out and see if its sellable. I found this broken ear for the motor mount. I'm sure this is a high stress area and I'm not a welder. Does it make this block junk?

If I May Opine........................
Been There Done That.........................NOT Because I Wanted To!
Its Been Known Momma Mopar Just Like Any OEM Had Engineering Development Stages With Powertrains . Many Still do...........
You Are Fortunate In That You Posess The "PIECE"....
There Are Ways Of Making This As Good As New. I Am Also Confident More Experienced Metallurgists Will Chime Too!
MoPar Did Have A Record Of Improving Earlier Blocks So This Area Wasn't So Prone To Stress Cracking & They Did Over Time.
When I Had This Happen Years Ago I Knew Of A Shop That Could "Furnace Braze". Typically A Commercial Heavy Equipment Machine Shop
Would Have The Expertise To Do This. Why You Ask ? Heavy Duty Stuff Like "Cat" "Cummins" "Detroit Diesel"etc are By Comparison Big
Money! So They Can Repair Stuff If Feasible. The Fact That You Have This "PIECE" Is Fortunate . It Probably Can Be Repaired.
In Addition ....... There Are Specialty Welding Rods & Procedures For Effecting The Same Result.
As Once Said..........."Choose Wisely My Son"..............
Best Wishes & MoPar2Ya!

No it can be welded. A motor plate using the water pump mounting holes to mount engine.

Wow, thanks for the detailed reply! It's a '68 440 so it's nice to know it's not scrap!

I have a 426 Hemi block that was "windowed" back in the day on both sides, it was welded back together and put back into the race car and continued to be used for some time.
It can be welded with a nickel rod.

If the block is rebuildable, cylinders ect are ok, or if it's a good running engine, then it will be worth the effort/money to have it welded. Find a shop that knows cast iron welding. They more than likely should mention using nickel for the job.
Good luck!
Good luck!
I have a block with a broken ear in my Roadrunner right now. I'm using solid mounts. If any problems arise, I'll post them. ruffcut

You probably won't need "the piece". A professional welder will weld that whole area solid for strength,and then grind to correct contour and re-drill hole. Shoot some paint on it and nobody will ever know.

It is very easy to say "go ahead and weld it." If you don't want to "damage" the block, take it to a professional. Not a practice as you go type of job.
Cast iron is not the same as welding mild steel. The block will need to be heated up, special rod and experience come into play. If it doesn't matter , go ahead and take a shot.
But if you want to reuse the block for sure, have it professionally done and you will sleep better at night not wondering if it will last or not.

He pretty much stated that he wasn't a welder so don't think he was looking to do it himself.

A really experienced welder with cast iron can weld that. The easy solution is to use a motor plate unless you are going for "stock" appearance.

I would still recommend a tie-down strap on the driver's side of the motor (aka chain it down) to make sure it doesn't break again.

Thanks, everyone, for all the replies! There is a good shop in town that fixed a similar break in a different block of mine by brazing it. The block is for sale and I didn't want to play it off as an easy fix to a potential buyer.
