Hi guys any body put a 4.3 in a tracker. It is suppose to have a s10 frame.
Have a good torch and a big welder just wondering what problems I may run into, including computer. Have a few blazers around, my daughter blew her motor and it is hard to find a 2lt 16 valve tracker motor

 

Richard...sounds like a awesome idea...but check with your local
Emissions laws first....most places state the engine
must match the VIN plate code...ask me how I found that out..
But the match up would give that vehicle the power it deserves...
But the swap should go easy if you have all those tools..
Just swap all electronics over from the donor vehicle.
And you should be good to go....include the motor mounts
And throw in the tranny as well

 

Trans mount, new custom drive shaft and exhaust system also

 

Sounds like a pretty good idea. I have a Tracker and Blazer in the driveway too. Would be a monster with a 4.3.
