Just tossing this idea around in my head. Wondering if it's worth it to dump the LS6 intake and swap to Victor Jr EFI intake for next year. I'm getting a forged 347 built and a I'm going to spin the D1SC pretty hard to get around 14-16psi out of it. I'm looking to make around 750 rwhp since I made like 650 pretty easy at only 11psi on the stock bottom. I'm also going to a auto and I'm shooting to run 9's next year at over 140. I know people have said the Victor Jr is better at spreading the fuel around but I'm just wondering if it's worth anything on a little 347? Plus it looks damn cool under the hood!

You will most likely not see any gain running 750rwhp. Check out this post https://ls1tech.com/forums/forced-induction/605899-reason-switching-carb-intake.html
Stick with the LS6

I agree, unless you want it for the visual appearance. Of course you could also hold off for the new Wilson intake. They told me today they will most likely come out with a tamed down street version of it. Bob

What is this new Wilson Intake you speak of? got any links? Pictures?

LS6 intake for your combo should work just fine.

Hi Ron. Yes I did, and I gave them a call. We have a customer from Maryland spending the week with us, and he was very interested in that new intake. The guy at Wilson said the current one is meant for large cubic inch engines, and the rpm range starts at 4500 rpm. Bob

Billet Bank Sheet Metal Manifolds

Wilson Manifolds has applied the same technology used in our one-off custom designed billet bank sheet metal racing manifolds to our new line of Limited Production Billet Bank Sheet Metal Manifolds. By producing these select manifolds on a limited production basis, we are able to provide a much more affordable manifold that fits the most popular cylinder heads and produces excellent overall performance in many high performance and racing applications, particularly with larger displacement and/or high RPM engines. They also look great on street rods and show cars and are designed to fit under stock hoods. These manifolds are ready to bolt on out of the box and are designed to accept Wilson Manifolds high flow throttle bodies and ultra high flow fuel rails as well as Nitrous Pro Flow direct port nitrous systems and manifold pressure relief valves.



These designs were developed using our state of the art solid modeling software, and each manifold's cylinder banks (flanges and runners with integral injector bosses, stanchions, and direct port nozzle bosses) are machined from billet 6061-T6 aluminum on our simultaneous 5-axis CNC machining center. Each manifold is then precision fixtured and heli-arc welded for a perfect fit and maximum structural integrity. This production method allows for optimum runner to runner and manifold to manifold consistency in terms of both geometry and performance.

Vortech, I'd run a LS2 intake/90mm TB for your combo. No need for a carb intake.

PSJ-I thought about but you cannot run the GM 90 mm TB because it interferes with the blower bracket.

I've seen that intake in person at the World Street Nationals, they said they were testing it out along with a n ew ball bearing throttlebody. Those thinks are truly works of art, I'd literally set them on my coffeetable.

i love that intake....

Bob, you say it Starts at 4500rpm... with its shorter runners, you think this intake migh tbe for higher than normal rpm. Basically, will it still make decent power under 4500 to 6500 or will i/someone need to rev the motor north of 7k to really get the advantages of this intake?

I have been ask santa for this thing for ever now....

now, anyone can think of a good reason why this cannot be used with a FI kit? Besides the price, which is north of 3500.00 in dollars, and getting it to fit a f-body, a vette shouldn't be a problem.... it should be fun atleast!!

Gaby@Wilson Manifold

We have no such "street" manifold planned. Our main target goal for the billet bank was larger cubic inch, high rpm, and/or forced induction applications. However, this manifold has been tested on high rpm, stock displacement N/A drag applications where they have seen as much as 75hp and 3 tenths quicker times. We still want to market this manifold for the larger cubic inch applications, simply because most average street guys will not need it. I ask that if people have questions about their particular application, please call the shop. We will try to steer you away form this manifold if you do not need it. On a high rpm 347" with over 750rwhp, it will definitely outrun the FAST manifold.

yes, but will it be as shinny in person as it is in the pics? Sorry, gotta ask the hard questions...

How would it par with a 402 w/900rwhp? Notice a difference from a Stock LS2 Intake?

Gaby@Wilson Manifold

In a 900hp application, the difference between an LS2 manifold and the billet bank is like a stock 69 GM 2 barrel manifold and a sheetmetal.


In all seriousness, the more hp, the more rpm, the bigger the motor, the more the motor is going to want our billet bank.

reminds me of a viper. A twin turbo setup would be pretty serious on something like that.

Gaby, I run a LS2/90mm combo on my 346ci with my 88turbo, you think I'd see a gain over this intake? Assuming I only mine to 7500.

i spoke briefly to a rep at wilson, not sure on the name but i was told that this manifold really make its power like a sheetmetal intake and from 4500-9k. Also, he suggested that this manifold really isn't street-friendly.

Those this sound about right?
