Hey I'm new here. Picked up a 98 gp gt with a blown motor. I picked up a l26 from a 06 Lucerne and got to work with info I found here. In total I had to change the coolant temp sensor, o2 sensor, and the upper intake manifold. Everything else was plug and play. I even kept the newer style torque arm mounts and alum oil pan ( had to clearance the u mount a little ) all in all I want to say thanks for all the info posted on this site. I wouldn't of attempted the swap otherwise.
