engine swap

I have a 94 Sierra 1500 SLT Z-71 with a tired 305 engine and my son and I are looking to replace it with a 350 (which I should have ordered it with initially!). What years and models will enable a swap without changing wiring, fuel system etc. Seeking a clean proper replacement. Will a change...

how much trouble would it take to upgrade my 2.2 to a 2.4? i have a 2000 sonoma sl with a 2.2 5 speed manual, and i have a 4.3 vortec sitting from a 93 astro van and was thinking about if it would be possible to just take my motor out and put the 4.3 in?

I was wondering how much it would cost to replace the 262 in my 94 1500 with a 350. I know it's an older truck but it's in good condition and honestly, it's a project I would like to undertake. I'm comfortable doing all the work myself and have a couple friends who can help me if I get in...
