Is the 1974 B20 block to be avoided? 200 1975

Hi all,

my 1975 B20F engine now has zero compression on cylinder #2 from broken piston-rings.

Of that, I am certain.

I am taking for granted that the cylinder-wall must have been deeply scratched and gouged, by now.

I have not even removed the cylinder-head to check the condition of the dead cylinder as I am too much in a hurry to get the car running again.

Rather than consider fixing and investing in my 1975 B20F, I am starting to look for a good replacement block.

I have located a 1974 Volvo 142 with a B20F with 95,000 miles.

I have read here and there that the 1974 B20 block-casting is 'soft' and porous.

What is the consensus of the B20 Brickboard-experts on the subject?

Should I or not give that 1974 B20 block any consideration as a replacement block?

Thanks in advance for all sensible advice.
