I have heard that you can swap a 3.4l rwd out of a camero or firebird into a 1986 s-10 blazer. If it's true let me know and if you know exactly how much modifieing is needed.

 

it actually should be fairly straight forward the 3.4 is just a bored out 2.8 and the 3.4 is a factory replacement for the 2.8. it should be a direct replacement and the only modifications will be to the fuel system iirc. im sure someone with a little more knowledge will chime and be a little more in depth with the description.

**Edit, im not usually this knowledgeable on engine swapping subjects but youd be surprised at what a simple search will turn up
