Hey guys, need a little help in an area that I'm not so fimiliar with. I have a 1979 GMC high Sierra with a bad (4.1 I think) straight 6 in it. I'm looking for the most economical way to get it going again. I have ran across a 250 straight 6 out of a 1969 c-10 on Craigslist for a decent price.
My question is will the 250 be a direct bolt in replacement for the 4.1?

Thanks for your help!
