So it took me 18 hours to pull my old motor never done this before in my life the hole time calling all the people i know asking for tips

Hi all I am new hear. I have a 2002 blazer 4.3 rear wheel d. 2door that i just changed
engines in. my old engine blew the mains and every told me to just get a new one.
So i got on line after saving up $9oo and got a new or close to new engine the carfax said it came from another blazer with 36,000 miles im am hoping this is true. I can not afford to send this to the shop to have a pro do this and have never changer a motor in my life i do have some mechanical skills and this is a big job to jump into.
