1994 Chevy k1500 z71 motor swap


Asked by Sep 16, 2015 at 10:42 PM about the 1994 Chevrolet C/K 1500 Silverado Extended Cab SB 4WD

Question type: Maintenance & Repair

I'm having a hard time trying to find a motor
to put into my 1994 k1500 I want to vortec
swap it but I'm worried it will be a huge
project due to installing the new computer
and wiring harness with it. Is there anything
else I should worry about with that or any
other suggestions and motors that will fit
right in with no hassle that are cheap and
easy to find?

I did this on my 1995 Silverado, you can get a different intake manifold threw Jegs, P/N 809-12496821. Then you can hook the motor up the way your old motor was. Interchange parts to eliminate crank shaft sensor & cam shaft sensor, from the parts off you old motor. You will need the driver side exhaust manifold for the Vortec.


Forgot to mention, then you do not have to swap out the computer & wire harness.
