Default To use or not to use LS1/LS6 Intake Manifold

I have one but I do not know if I can justify it for the mods I am doing. I am doing the 212/218 high lift cam what do you al think. Is it worth it or should I sale it?

Maybe some others will give their input here. I know the LS6 intake swap has been done here by some. Just from what I have read though the LS6 intake flows more in the upper RPM ranges. You might give up some on the low end with the swap, although with that cam being lower duration and likely more torque it might not be that bad. What torque converter you running? I'm not sure what the RPM range of that cam is, but it might not take much advantage of the higher flowing LS6 Intake.

Not saying its not worth it, cause I really don't know, but it would be worth looking into at least. Keep us informed.

What are your plans for the truck? I'm liking these Vic Jr swaps people are doing. And I'm wondering what a FAST 90/90 setup on one of these trucks would do... especially on a FI truck.

Do the LS6 if you already have it.Its ok if you dont go over 6k RPMs.The LS6 will help evan a mild motor.
