The 3yr /1yr warranty has been that way for at least a couple of years. I found out at about that time when I thought I was going to have to replace my 350 in the 34. If he puts it in the 85 C10 he should be good to go with the 3 yr. Was the $1700 for the 290 hp 350 or for the 260hp model? Last year you could get the 260 hp crate 350 for about $1400 from Summit or from a nearby dealer that sells nationally (Apple Chevrolet in York PA). Regardless the 350 crate is the way to go, especially if you plan to add your own goodies, like preferred intakes, carbs, cams, etc.
