Recently I cracked my cylinder head, but have yet to see if it's damaged beyond repair. I've heard it can be fixed w/o dropping a whole new engine. Is this true? Depending on costs, I may repair the one I have now, drop a new 6.2 in the Blazer, or drop a new chev. 350 in it. The Blazer w/ 4" lift sitting on 33" will be moved to our beach house where it will be used seldomly, about 6 weekends a year. Which engine( if either) will be more reliable at cranking up after months of sitting. I would like to keep a 6.2 'cause we'll be pulling a boat with it. Would i have to swap in any adaptors to put in a 350 if it was built originally with a 6.2. Thanks for any advice to any of the questions!
