Cylinder wall weld??

Thanks for all the answers!

The story is actually I just broke my 0.30 over 360 block of my 408 stroker as the lower oil rings of two pistons broke and left deep scratches in the cylinder 1 and 4.
I first thought about fixing it with two sleeves but with the machine shop prices over here that is even more expensive than finding another 360 block and bore it 0.30 over so I can reuse my stroker rotating assembly with forged pistons.

The 318 was in the car before when I bought it and I drove it for maybe 1 or 2 years, ran quite strong and took some abuse but it started leaking in a lot of places and I thought the head gasket maybe gone in the end as I remember I the radiator hoses always had extrem pressure - so with this repair I think that proved right.

Because it can take a while till you find a 360 block here and the 318 is a 1969 with the higher 9.2 compression I thought ill just clean up the bottom end, put the aluminum heads and air gap on, and a comp XE274 cam which I have laying around and see how it works, maybe drive it for a year till the stroker short block is sorted out...

But with this damage I think thats not even worth the effort and actually just 2 hours ago I was at a guys garage who said he can find me a 360 block quite easy so I guess the 318 project is not happening now :(
