cracked block, repair

I recently aquired a 72 429. I have not torn it down yet but have noticed a crack in the rear of the block at the water jacket. The engine has been sitting for years and I have yet to begin to tear it down. My question is if this crack is restricted to this one location only would having it welded by a pro be good enough to continue with the build on that block. I have already decided to replace the D2VE heads and was wondering if I should strip this motor and start with another.
Any suggestions would be greatly appreciated

well i think if you know someone thatr can weld cast good it should be fine i am a welder and cast is very tricky to weld so make shure you take it to someone that you know will do a good job i always try to find a good block befor repairing a cracked on but they r gettin tough and spendy to find now days. if you decide to keep the block and get it fixed it should be fine

Ive seen cast iron heads welded with a mig welder. Gotta clean the crack good and use pre-heat and use someone with real good experience

I think I'd fill it with water and see if there are any more cracks - was it frozen at any time? Could have another crack lurking somewhere.

That is what it looks like to me. I will take it in and have it checked. If that is all I will get it done properly, if anything else is there then I guess I may as well start shopping for a complete 460.

Thanks guys for the responses
