A real build not nickle and dime wannabe junk

Great. I'll have to give that a try.
I'm mostly interested in repairing cracks in combustion chambers.
Uncle Tony tried welding a 426 Hemi block with a HF Flux core welder...the block sent a rod through the side he was going to stitch it together and solid fill the water jackets...I wonder how far he got with it before he up and quit...
