LA 360 or Magnum 5.9

I guess this is what I've been trying to say. If you can find a 5.9 magnum with around 100,000 miles (mine was 92,000), just do rings and bearings. If the heads aren't cracked then run them. This will be cheaper than building the 318. Best of Both worlds. I paid $300 for my entire magnum engine. Still running the stock short block.
I can't find any magnum local under $700. I have looked and looked. If I could find one I would build it. Texas is bowtie country.
