Not Ranked
Lineslinger M couple of things, Any motor can be welded up with the correct procedure. Block has to be heated to 600f for a time and special rods are needed to weld with. They do 2-3 heat cycles. It then goes on a stress table for some time and test the weld area. If OK the section of the block is stronger than anyother. Keep checking on E-Bay. Does it have to be a SO block?? 90% of the people wouldn't know the differents, Cobra nuts that's a different story. I am not a machinist but in the old days when motors cracked alot of them where welded. What are you going to do with this car, cruiser, racecar, waxer, Under easy care I would bet 20$ that motor will hold with a weld job and good machine work for truness. I will look for a couple of articles on welders who do this. You put side bolts in a 390 with caps and no one will see the differents. Last question HOW much HP&TORK are you looking for?? Answer these Q&A and maybe you found the answer. Rick Lake. Ps if you are going racing or building a top notch car you maywant to go with the Shelby or Genesis block. The Alum blocks are 90 lbs lighter than iron, in a cobra that's alot
