340 coolant trouble

i've been working on my car since i could hold a wrench my older bro bought it when i was about 3 and spent countless hours helping with all those tight spaces, i think i was the only 5 year old who could do spark plugs faster that an adult, but anyways great story, i love hearing about long time resto's and car history, good luck on the build, cant wait to see pics:read2:
