ls7 head to ls3 intake adapters Anyone ever use these? says it will adapt ls3 intake to ls7 head port. Was thinking of a super victor ls3 with 4500 flange. Being there is limited intakes for carb ls7 heads im wondering if these work.
Manifold im talking about is Edelbrock 2821.

The ports are a lot different. I don't think there is enough material in an LS3 manifold to grind out and fit the LS7. You would at minimum have to make spacers to raise the manifold up for the port roof alignment, and then fill the floor of the manifold about 1/4".

Those intake manifold adapters would work perfect for what you are looking to do. We make them for standard and tall deck blocks as well. It will allow you to bolt pretty much any LS3 intake manifold to LS7 heads. We originally made them for the Whipple blowers but they have released a LS7 base. There was also a redesign we did to the intake ports on the adapters. They are now a lot smoother. Pictures posted of some close ups.

There you go Violence. A Super Vic with a Accufab 4500 t/b.:-) You will still come out cheaper than the Mast intake and yours will be completely done with rails and injectors.

That manifold is not even close to what it should have been. They waisted their time building it. If you spent 1000 welding and porting it it might be close to a mast.
Have not touched the car. Until I get a engine and trans for it I am not even going to start on it.

Super victor has been tested on what? If you use it in the right application it will run better than the jr. In what scenario would a mast be better? I'm just curious because that's a pretty blanket statement. You realize that a mast comes one way, and with manifolds one size does not fit all.

So Tim you think me switching from my Vic Jr and 4500 adapter isn't worth switching to the Super Vic? If not I could have the Jr ported to match my heads and adapter.

Mast intake, or any other shelf intake won't even come close. Runners are way too long. Whatever intake you get it'll have to be a custom runner length, or have to be worked on. No sense in spending $1500 on a mast intake that you'll have to put another $800 or so into. If going that route, get an all-pro "as cast" intake, and have it ported.

It's a cast unported intake. Of course it's going to need some work. I wouldn't use that mast intake for a door stop. I guess if someone has money to **** away on a pretty intake, that's the way to go. If someone wants to go fast, they need to spend their money more wisely and have a manifold tailored to their engine program. Again, one size does not fit all when it comes to manifolds.

About the same as the Mast. But could one of you guys answer my ? about whether to have my Vic Jr ported or just spend on the Super Vic. Both cost about the same $450.
I will say this John B. 427 Did Not make that much more power with the Mast over the Holley High ram or his Sheet metal intake 700rwhp all were very close. So if you want a good cheap intake Holley High Ram have it ported and open it up for maybe a 105 T/B.
