I have a 94 s10 blazer 1st gen it had a 4.3 vortec in it well I bust the motor and I have a motor that I'm wanting to buy but it's out of a 99 chevy truck could y'all tall me if this is going to work in my blazer and if so what all will I have to do

 

first, let me say welcome to the show.

second, this isn't the section to be asking tech questions in.


but i'll play nice and answer your question for ya.


simply put?..................no. not even close.


if you saw the engine, you'd notice the major difference in the intakes.

never mind the wiring & computer differences.

you're gonna need a '92 to '95 W-code engine.


sorry to hear about your broken beas.

 

As mentioned this isn't the place for tech questions.

*Moved to Engine and Transmission*
You'll most likely get more answers to your questions here too.

Welcome and no you won't be able to put an engine from a 99 into a 94. Like Old Skool said, the differences are MAJOR, and you'd have to redo all of your electronics to run it.

The 94 is an OBDI computer, while anything 96+ is OBDII.

Keep looking, and if you can't find anything you can always do a 350 swap from a fullsize truck of the same era.

Rich, you beat me to it lol, I was editing my post when you moved this.

 

Someone told me that if I put my intake on it that it would work with my computer that's in my blazer does that sound right

 

I wouldn't bother putting in another 4.3 get something with a little more *****, they make kits for 350's you can find a used one of those for cheap, save yourself the hardship of electronics and get carburetted!
