there was a post from fords tsbs about casting problems and how to repair them,and i did mentoin about probs at the mmc earlier,the crack in the lifter valley,can be brazed,dependinding how close you are to the lifter bores,my machinist,welder told me could warp the bores,if you have it welded/brazed,put some old lifters in the bore as heat sinks,and when done measure the bores for roundness,i also had a friend that spun # 3 main,tore up the thrust face,block,and cap, the old school welder machinist,passed now,brazed the block and cap,machined them,to fit the thrust bearings,line bored it,still ok 35 years later(427 block)and according to the ford service books ,and the thechnical bulletins,they just used epoxy to correct non stress area casting flaws |
