i heard the 98 ls1 fbods were different than the 99-02's can anyone fill me in on whats different?

 

I believe the 01 and 02's have an aftermarket intake from the factory? I know theres something different between the intakes. With slightly more power.

 

'01s and '02s have the factory ls6 intake. Same as the z06 except a different part number for some reason.

I've heard '98s have a slightly bigger cam though?

 

Ls6 intake thats why I kept thinking aftermarket thanks. For some reason I never think about the ls6.

 

the 98 cars have a unique pcm that is somewhat of a limitation when going f/i

 

From what I heard the 98's had computer issues that got worked out in 99+ cars. I doubt the cam is bigger. The 01+ cars make 5 more horse

 

Thread with all of the differences.

And actually the 01-02's had a smaller cam than the 98-00's.
