Cobalt not sure where you are seeing mild aftermarket cams running 800-1200 and think you can't use the gmpp springs with them but OK.
Also not sure what data you have seen in person on a chassis dyno with this swap done in a truck but I can tell you from experience its great if you are looking to brag about peak numbers.
The reality of it all is you will only net a nominal gain at the top end and lose the torque on the low end which the trucks need to move their heavys asses!
I have spent a ton of time on chassis dynos and see this all the time.
As I stated, if it was my money I would put an aftermarket cam in that is designed to work with my combination and not the combination of another car, truck or engine.
Again if that is what the op can afford then go with it, that is the reason I posted how to do it from experience.
