Im building a mild LQ4 for a work truck that will see some moderate towing. All I plan to do as of now is add some lightly ported 243 heads, Comp Cams 212/218 LSx Cam "HIGH LIFT", long tube headers, a tune, and a good exhaust. This engine will never see 6000 rpms. Would adding an LS6 intake be worth the trouble, or will the factory one off my 04 LQ4 engine work well at the lower rpms I will be running?
Wouldn't be worth changing all the accessories, water pump pully, alt bracket, crank pulley. Stock intake would tow better, no low end loss. Are you adding a converter?

Nope. Staying with a stock converter.
I'd stay with the stock intake or a TBSS intake

i did the swap back in the day and gained nothing. the truck manifold is under rated IMO.
