I have a 4.8, can I put any LS1 Intake Manifold on? See I have no clue when it come to this stuff. If not is there any aftermarket intake for the 4.8?

any ls1 or the related manifolds will work. truck manifolds flow better than ls1, ls6 is better than both. F.A.S.T. makes an aftermarket manifold too...and i dunno what else.

Wait a minute!! Will this be your only mod???? If you dont have a cam, heads or headers. Or all of those mods. The LS1 intake is really pointless.

Ahh see thats was the answer I was expecting! I ant got shit lol. I have Intake and exhaust.

So let me ask this can I do a cam next? If not what should be next? Headers? Program?

Heads sound a little more serious than I want to go.

cam and headers would be nice...tune to bring it all together right.

any intake for an LS1/LS6 application would work. FAST/Weiend/BBK, etc. You just have to move your accy's around to clear the new intake since its MUCH lower than the factory truck intake.

with a cam, longtubes, and tune, a FAST intake would make pretty good gains.

stick with the truck intake until you are making silly power or trying to spin it to the moon... a moderate cam and long tube headers will help you more at this point...

headers and tune are the are a good start. I'd look into that and depending on what you have you may be able to get rid of your EGR & AIR to clean up under the hood a little more when you do the headers and tune as well. small additions to the trans help too, stuff i have yet to do.
