Where are you seeing all this talk?

Basically......6-8" straight shot from filter to throttle body with no turns > CAI kits for LT1s which have two 90* bends and over 24" from filter to TB

Just guessing on the distances but I feel they're conservative.

LS1 lid helps throttle response and gives documented gains in HP across the RPM range. But you have to cut your core support to make it fit.

If you don't want to cut the hood, you're gonna have to drop the radiator as far back as you can and make your own supports.

Ls1 and lt1 cars use different core supports that's why the ls1 lid isn't a 'bolt on' swap.
There is a ton of info on this site if you search for it. At least 3 write ups I would say. Its a pretty involved process.

I'm debating right now if I should try it or just do and 'over the radiator' style intake so I don't have to cut my ss hood.
