ls6 intake flows less then the GMT900 intake, flows less then the GMt800 intake

 

I'd like to see the data on that. I've heard it the other way around. Never really looked into it.

Anyway, only reason I suggested ls6 is because it might not require mods to work. Thought the alternator bracket and a couple other minor things made the 900 intake not a direct bolt on.

Might be even money anyway, the 900 intake is a lot cheaper.

Cam swap is going to be where most the improvement is made. Even with the 78mm intake.
