Allright guys, I am either really screwed or opportunity is staring me in the face... my DD is an '83 silverado c10 2wd w/ a 305. Last night it threw a rod (I think), sounds like a box of rocks and an angry herd of badgers when I start it up. Really bad. My '73 K5 is safely tucked in the garage, where she will stay until spring. She has a stock 350 with headers and HEI. Buddy of mine just called from work (I can't be there, my truck is broke!) and may have talked me into the following: He brings his cherry-picker and tranny-stand and what-not... We use my heated garage (this is Minnesota, it's about 10 degrees right now) and my tools... Pull the 305 and put aside. Pull the 350 out of the K5 (leaving the headers, probably), and install into the C10. This winter, I research & buy a crate engine and plunk it in the K5. Result: The wimpy C10 comes back to life with a significant power upgrade, the K5 gets... something... Here is the rub: I have never done a swap. I have a little $ to work with but not a lot, and I have no wheels 'cause I am NOT subjecting the K5 to MN salt. My friend makes the whole thing sound easy... says we could do it in about a day and a half. I need advice! Help!
