I have thought about trying a intake like that also, but I will stay injected. Maybe not on the 6 but I have been looking for one for the 7. Not many results to be found for what fits fits under the cowl. I don't mind trimming the cowl but would like to know if that style of intake is worth it.
7500RPMs would be cake.
Do NOT run an elbow.. It demolishes power gains on a NA combo. FI it can work.
Cowl would have to be trimmed.. I'm still looking into the hood.
Not gonna happen from a roll: stalls hurt trap speed which means they hurt you from a roll. From a low roll however, a 3600+ stall will definitely help you until you wind out 2nd gear then it starts to hurt. I'm not bench racing either, proved it with back to back comparisons before stall/ after stall and again after I changed from a no name stall to a top quality (ie efficient) SS3600 stall. Freeway roll racing is something I cringe at because it's NOT where my car (or any other stalled auto) shines.
both cars are animals... if you ask me. The 5.0 has the motor and gearing advantage. And the Z has the weight and aero advantage. Not that im into bench racing like this. But as far as both cars getting an intake is concerned. The new 5.0 will pick up more power and grab another 500rpm with the boss intake manifold then the z will pick up with a ported fast. So if anything... finishing the bolt ons would swing the 5.0 with the advantage. Ive been a die hard LS guy my whole life... but these new 5.0s are just so incredibly efficient its not even funny. Lets not get into what the boss motors will do. Upper 400s with bolt ons. The ls7 was my dream motor because it was so responsive to even the slightest of free mod/ricer bolt ons. The new boss motor is even more responsive which is why i ended up buying one. But personally i dont think there is a loser in this race. The bolt on c5z is a serious car. Hell a stock c5z is a serious car. The vette wins for having the slight advantage in pull in the race, and of course owning a c5z lol. But the guy in the GT also wins because he has a standard issue bolt on mustang GT and he is right there with the Z. Great races... great results. I would like to see how both cars would do with Intake manifold swaps 
Rematch anyone?
Rematch anyone?Also, IIRC hasn't the Ls1 put down more RWHP on the dyno than a 5.0? I'm sure the 5.0 will surpass it at some time but I'm pretty sure the record is still higher for the Ls1.... Let alone an Ls7.
Aren't you planning a stock cube build with 317's or something like that? A ported 102 would be plenty for a setup like that. Heck a ported 90 or 92 would work great for a max effort 346.https://ls1tech.com/forums/14581559-post38.html
Ls3s- https://ls1tech.com/forums/14592833-post48.html
There is plenty of SI cars out there running the 102. It will make more power, period.
That was my old build... I was running a ported 102 on the car with the 317s, it ran extremely good for the mods.
My old ported 90 with the Ms4 car would have loved to be a ported 102, but they weren't out yet.
I'll lose torque down low with the new setup but with a large converter I'm not too worried about it.
65+whp from full exhaust, air intake, and tune. Typical ls7 gains from the same bolt ons are around 55-60whp. Call me a ford fan boy all you want. Just said i was a die hard LS motor fan, its all ive built in my day. Built motor to built motor, yes the ls7 is much stronger... its 2 liters bigger. Thats common sense for principles of air flow. Im not saying any of that. Im saying, stock ls7 to stock Boss 5.0, the boss gains more power from the same bolt ons. But its a built 5 liter out of the box and it will rev 8000+rpm
And yea.. You are right.. CI. does nothing the farther the race goes. That is definitely not why 427 Ls7s get absolutely stupid at 120+mph. There is a reason you have to put SEVERAL lengths on them down low to hold them off up top, they don't ever run out of stem.

Bone stock?
I have my assumptions of why you said this and are laughing... Both assumptions boil down to the same conclusion.
Yes, stock for stock or mod for mod an Ls1 will always pull on a mach 1, the longer the race the larger the gap. Stock for stock the Ls1 has this advantage.. It has more cubic inches and responds better to mods, why would this not keep holding true at even more of a gap when mods start going on?
I'm not sure why you are laughing.

Negative, I have yet to see one trap over 110. Had a guy with a built stroker motor with a tko trans making about 410rwhp and it averaged 116mph traps, he put an auto in it an it would be lucky to trap 114. Cam only auto ls1's are doing that.

Ls1/2/3s don't freight train things up top like the Ls7. It is cubic inch. 427 is hard to **** with at 120+ MPH when a 346 runs out of steam. There is a reason an ls2 pulls harder up top than an ls1 in the same exact vehicle... There is a reason Ls1s freight train 4.6 Mustang GTs. There are most definitely other variables... One of the largest? Displacement.

Again I am laughing at your delusional thinking process.Aero mods
Autos have been 116+ with bolt-ons alone.

Displacement no because they damn sure want freight train all 4.6s. I will have to disagree on your ls1 mod for mod pulling away machs pick up alot with bolt-ons. I guess the new 5.0 responding just as good if not better to bolt-on mods compared to the bigger cubed ls motors is a myth Again I am laughing at your delusional thinking process.
Aero mods
WTF Autos have been 116+ with bolt-ons alone.

Again I am laughing at your delusional thinking process.Yes, Mach1s do pick up a decent amount with mods... But not only do Ls1s pick up more per mod, they start with more. And I'm delusional. You are actually arguing that mod for mod, hell stock for stock, that a mach 1 is equal to an ls1... Equal. Are they extremely close stock for stock? Absolutely, within a car length or 1.5 lengths. Mild bolts ons? Pretty much. Full bolt ons/cam only/etc... No.
Better? Absolutely not. Close, Yes. As stated, the Ls3 on average makes more power than a 5.0. Also, I am 99% positive (unless the 5.0s have a new record) the ls1 still has a higher RWHP record than the 5.0. There are huge stalled auto ls1s in the 42XRwhp area (built for the track, not the dyno).
I wouldn't keep putting them down if you didn't have a problem stating what I'm sure you know is the truth.
I'm glad you think its funny......?
