Whats the difference from an LS1 intake manifold and a 5.3 intake manifold?
The height. A pre- 2001 LS1 intake flows the same as the truck ones. But a 2002+ LS1 flows much better. Also known as the LS6 intake.Quote:

all years of ls1, ls2 and ls6 intakes will fit your engine.
Thanks. Is it s good sugestion to do this? Will my throttle body and other parts fit it?
Why would you want to swap to an ls1(I don't mean that rude).
I have seen 2 different flow tests of the stock ls1, ls6, truck, and fast intakes.
Every graph I saw the truck intake out flowed the stock ls1 intake until way up top into the rpm range(past 5000 rpm).
The truck intake is taller like Jeff said. That's a good reason why it flows better at lower RPM. I haven't quite figured out why it flows better at higher rpm yet.
I figured it was better. I am new to this type of engine. Thanks for the info. I'll stick with what I have.
I think there's a write-up on that in this forum. The year you want is from '01 to '04. I don't think it's really worth the swap unless your planning on spending a lot of time in the higher RPMs IMO.
If I were to pay money to update my intake I would buy a new Weiand composite intake. Makes more power than any other out there that I've heard of and its reasonably priced unlike the FAST intake.
