I hope they make this!

If they want intercooling under the stock hood, they should work with Alky Control to put methanol injection ports in the manifold.
And in any case, anyone building an engine that can handle 25 psi of boost has got the cash to put a hood scoop on the car.

25 PSI and no intercooler sounds like a lot of hot air?
More power than naturally aspirated but I'd like to see some data showing intake air temps and mass air flow. Guessing that 10 psi boost and properly intercooled will have similar mass flow as 25 psi and no intercooling.

After owning a few CTS-V's, I certainly would have preferred a roots style blower for my Impala build.
When I started the Impala rebuild in 2020, I would have happily paid 15K for such a creation. (I believe) that beyond 15K, and the LS swap is the smarter move for big power. I had investigated the eccentrics who "thought they could" do a roots on an LT1, but there was no working prototype that was available or could be recreated. I even searched out Keith Meese before I decided that wasn't the best option. I would NOT have given 15K to stranger who simply says he can do it because he has the cad file to machine an adapter plate, and I wouldn't give a penny to someone who feels the reverse cooling flow on the LT1 can eliminate the need for an intercooler on a roots blower. No one is using a Whipple to get anywhere near 25 lbs of boost (or 1000 hp) without a great intercooler.
Right now, I am 9 months pregnant with my RMCR Impala, but I would still gladly consider a Whipple (or similar) if there was an adapter AND and intercooler that worked without super-heating the boost charge. (Yes, I would be happy to bump out my hood to make room).
With all blowers people tend to underestimate the heat caused by compressing air. Even with an OEM designed intercooled system, just bumping the pulley size down to make more boost can create enough heat to bring down the horsepower overall.
Back to Impalas, in 1995 I had to spray a 75 hp shot of nitrous into my Vortech/Impala SS throttle body, not for any power boost, but just to cool down the compressed air from the centrifugal blower. Heat kills power, and superchargers make heat. Meth injection, gaseous intercooling, and even nitrous can combat the heat, but I would certainly want to see an intercooler on my Whipple set up.

To quote LT1 tech and performance:
"This is a Gen 2 LT1 / LT4 Whipple supercharger kit that's in development for C4 Corvettes and F-bodies."
"... it will come with the supercharger intake manifold, supercharger mount baseplate, supercharger intake box, cold air intake, fuel rails, bypass valve, 160°F thermostat, and the other things that are attached to the stock intake manifold ..."
Thing the 1st:
B-cars have much more room under hood than Y- & F-bodies - yet once again, B-cars are an afterthought ...
Thing the 2nd:
Is there such a thing as an LT1 larger than
408 Cu In (6.69Litres)?
How much more power do 408 LT1 engines make, compared to 396 LT1s?
How much more power do 396 LT1 engines make, compared to 383 LT1s?
...
What I'm trying to get at, is how much (more) power LT1 heads are capable of making, and how much the bottom end is capable of withstanding.
Point is, I don't see an IronBlock LT1 - 408, 396, or 383 - capable of either withstanding or making 1000horse, without spending enough money to make an LQ4 / LQ9 conversion a better value.

I don't see why a supercharger kit for a late model smallblock wouldn't work. All you have to do is put a blockoff plate over the distributor hole.
This would keep me from wanting to LS swap honestly
A little late coming into this thread but I am talking with someone who can do something like this a whole lot cheaper. But what I need to do is find an intake that is different than the stock one. Basically he already makes LS adapter kits to bolt on Whipple style super chargers. He also builds air to water intercoolers as well.
Right now he starts from either a Magnuson SC tub or a high ram intake where you can pull off the top section.
We have talked about my sending him a stock intake, him shaving off the top, making a TB block off plate then making a weld on plate that would go on the intake. This would then allow his intercoolers to be used. He can make them any thickness. Last time I talked to him he was making a 6" one. When used with the Magnuson tubs on the LS motors his 6" intercooler sits inside the tub and I believe you can easily close the hood on top of it.
I saw a picture on Elwins engine site of some sort of intake like that. Would likely be well under $1000 for the adapters. Would be bolt on if can find a low riding aftermarket intake. I know very little about what is available for these engines. I really want to start looking at this stuff for next year.
