Hello I'm new here and I have a question regarding cracked block. My 390 block has 3 cracks in the lifter valley area I suppose you could say on the walls separating the watter passages from the lifter valley area. One is about 3-4 inches long on one side and the other 2 are maybe an inch in length on the opposite side. Is there an economical way (no laughing) to repair this or is the block as good as scrap. Any thoughts / advice would be greatly appreciated I am running low on funds so I am just trying to get back on the road that and finding one of these blocks in the Houston area is getting hard to do. Thanks again and excellent forum!!!
