This is a 454 Vortec motor removed from a running 98 Chevy pickup with 86k miles on it. It has been sitting in my shop waiting to be swapped in to my Dually but hasn't happend and I have come to the conclusion that it won't anytime soon so I figured it would be best for someone else to put it use. It will come with the harness and ECU. $500 or trade. You can also contact me at 832-405-6375.
