Doing an LS sway into my 86 C10. The motor is a 2008 LY6. I have a cam and all the bolt-ons. I was reading about a company that ports the LY6 truck intake with a claim of 20-25whp with their radical porting. The cost for this is $450 so would I be better porting this truck intake or buying something if so what? The truck is my DD so really looking for usable low-mid range power. If you think it's a complete waste of money to mess with it please let me know that as well.

They do very well when ported, its definitely a good route to go.
