Frosty,
Thanks for the tips. I actually have all the parts listed in the kit already except the Head bolts, Rocker Bolts and Head Gaskets, as I was planning on doing the LIM on the car.
I have an 04 GTP and have a slight knock. However, locally, a S/C 3.8 start out at around $1300, and all have 100K plus on them. I can get a 04+ N/A with 10K to 50K miles on it for around $400-700. So that is the reason that I am looking to top swap. I would have all the parts from the GTP and use the N/A, swap everything over and swamp the motor out.
I guess I will have to see if I can find some headers as well. Don't want to blow the engine right after a swap.
