i have around $2000 for the 92 4.3 i did in my 4runner and thats a ca legal swap but i did notice that the average cost for just a 3.4 motor was 1200-1500 and you can get the entire 4.3 donor truck or blazer for around 500-1200 on craiglist it kinda depends on how much you want to spend and i kept my 884runner 5spd
