305 to 350 84 GMC 1500 Motor Swap

Hello yall. I am new to the forum. My GMC has a 305 but it needs to either rebuilt or replaced, smoking out the back sometimes more than others. If I go with a 350 is it direct bolt/swap or would I need to change computer, mounts ETC. I am going to be replacing radiator, water pump etc that is easy to replace.

I swapped a 350 into a 1986 C10 with a 305. I used the 350 long block (block with heads), everything else was from the original 305. It bolted together and worked perfect.
