i think you need to sell what you have and get an LS7

 

I know my 15lb pulley will no longer make 15lbs. I could care less how much boost i make as long as i'm making lots of HP. I still say i should just do heads and cam on my current motor but everyone says the rods won't hold up and neither will the pistons. Heads and cam will cost $3000 installed and tuned. But, if i'm gonna break the rods or melt the pistons, what's the point? Changing the pistons and rods will probably cost at least $3000 i think. So now i've spent $6000 and still have a 6.0L. Is that the route I should go? I think I can use my stock fuel system that way. I should be able to be over 500rwhp with heads, cam and headers on my current motor and boost.

 

If it was me I would find a cheap 6L block get it bored/honed drop a forged eagle rotating assembly(i can get it for 2200) Do a valve job on the heads put a good set of springs on it and a cam=4grand plus whatever it is for install and tuning. Believe it or not you can do the install/removal yourself if you have a place to do it.
