Awesome.
I just finished swapping a new 350into a 1980 K20 with my daughter. I was really glad she showed the interest since normally it's all clothing shopping and boys with her. Now she has the biggest baddest truck at school and she's happy as a clam. How she managed to put 120 miles on it during the first weekend without leaving town I'll never know, but meh.
Anyway, welcome from BC, and good luck with the build!
