Looks like his reverse cowl hood is already tall enough for a CID and low profile 4500 TB / filter setup.

 

Gwatney ls3 intake shoot out showed the CID 4150 with elbow out powered all intakes in hp and tq. Said the 4500cid with a 4500 tb would have been even better and that was on a stock bottom end ls3.
your cubic inches would work well with it but may have to tweak the converter again to optimize it

 

Thanks brother. Definitely gonna ponder on this!

 

yeah, i thought I was being funny. Apparently not...

 

When we first built our motor we started with a Super Victor with a Holley 950 ultra XP. While we were on the dyno I had a 2" Wilson 4 holed tapered spacer I wanted to try. To our amazement it picked up 47 HP. The next year I found out that ICT Billet made a set of adapters to mate a LS3 intake to a cathedral head. We had pulled the motor to check **** out and decided to get the Cid intake and had Pro Systems build us a Dominator. From all our specs they came up with an 1100 Dominator designed for nitrous. We were kind of in a rush so porting the adapter wasn't optimal and it was at the end of the season so i knew we would do it up right this last winter and we did. Just bolting on the adapters CID intake and the new dominator the motor picked up 49 HP and 67 FT pnds of torque on the same dyno. Then this winter we fully ported the adapters and added a 2" 4 hole Wilson tapered spacer to it and it picked up .35 in the 1/4 on motor only. We run a halo nitrous plate from NX that we bought by itself and sent it to IS to be set up with their solenoids, and flowed with tunes. Well worth the money. We also added a self resetting burst panel plate open as well, each being 1 inch tall. That was another 2 inches taller. This was last year before we ported the adapters and added the Wilson spacer. It picked up .05 The point I'm trying to make is it appears that the more intake you give these motors the more it likes it. Next winter we are doing away with the adapters all together and welding up the Cid ports and having it ported to a cathedral. The best part is that it runs stupid good all through the RPM. Low, mid and high. Then you hit the juice and holey **** does it become retarded. Lol I know you guys aren't going to believe me but that cathedral nitrous motor sure has pissed off some supposedly bad *** turbo LS7 cars. We freakin kill them on the light. These AFR 245 heads are highly underrated. Tony did a fantastic job designing these heads. Can't wait to see what Bortous motor does with Tonys extra port work.

 

Careful there Mr T.
There are many LS7 fanatics here that might get pissed off. Lol
Your motor is quite mental with it's current combination.

Tony does do good heads that's for sure.
It's great how they pull hard all over.
I am curious to see what he will bring to the market next.
I think with the cathedrals, they are the best they will ever be for what they are.
First V1 then V2 and then Tony's hand finishing.
I don't think there is much room left to improve upon with this design.

 

Thats the best part thing about it. They Don'y Need To Be.

Don't mean to **** anyone off. Just stating the facts.
From what we have seen at the track and raced quite a few they really get pissed when they find out they got smoked by a cathedral headed motor. It really is pretty comical. I read all the same **** everyone says and yes there are some bad *** LS3-7's. But they are very few and far between. I go to three different tracks all the time and that is what we have found at all three. Most that use those big *** heads can't get out of the hole. By the time they get them hauling *** its too late, we already have many cars on them. Most of the time we have 2 cars on them before they pass the tree. Fact. I have the videos to prove it. So don't count the cathedral guys out. You just might get your *** smoked by one. Then What? If anyone wants to see a true bad *** racer that posts everything about his car and will tell you anything you want to know. Go the the racing tech section and check out Kennys 98 camaro thread and now he is doing a Fox Calypso build. Both with cathedrals. His 60ft is insane for a turbo car too. The man definitely has it figured out. No one on Tech that I have seen including us will come close to touching him.

Junk *** Cathedral Heads. LMFAO

 

Lol.
You are fanning the flame which is about to be lit.
I like your enthusiasm.
Purely NA though an ls7 head revving from 7000rpm+ would certainly win out though right?

 

Well I can't afford to switch heads along with the intake and throttlebody because I have other things to do to the truck this year and only so much budget to work with, so I will be staying with my Genx 255 LS3 heads. That being said I can afford to buy the CID intake and a 4500 throttlebody, just looking for a consensus that it will pick my truck up in the 1/4 mile over my current LOD intake. Looking at the CID website it appears the 4.5 version would best suit my 447 stroker? Is there a particular 4500 throttlebody I should be looking at over another?

 

I would 100% talk to a bunch of people before ordering the CID including the mfg. The 4.0 on our 415 was too big and the vic jr runs harder in actual use on the track until it runs out of steam in high gear. Did the CID make more power? Definitely. Was it as efficient getting down track? No. It would need a bunch of tweaks on the combination - and then probably would be a bunch faster, but also would require running the engine harder with more rpm, more gear, more converter, and more rpm on the transbrake.

For you with the extra long stroke you'll probably do great with the 4.0 out of the box. With just a 255 cc head I think the 4.0 will be better matched for the CSA. The 4.5 I think you need a way bigger head or else the runner taper will be messed up.

I think they'll recommend the 4.0, and yes you should definitely give one a shot

 

Hey, Appreciate the advice.....that's what I'm looking for

 

No problem - for reference that 415 made 660hp on an engine dyno with the vic jr and 4150 holley 750 btw. 243 intake lobe very mild 11:1 compression pump gas deal in a ~3100 pound malibu wagon. Your combo would better use the CID.

In January with the CID ran a 9.94@133 in 2000' DA. With the Vic Jr. I have tons of 10.0 passes in 4000+ DA summer races. A couple weekends after the CID run we put the Vic Jr back on to run super street 10.90 index with a throttle stop and it was running 10.9's at ~132.5...so no question the vic jr would be just as quick wide open just very different in how it gets through the track.

 

Some great info. To be clear on the intakes for any non regular members that might read through this,
I think the victor junior intake that spanks13 is talking about is an LS3 version (correct me if i'm wrong), which is a much better intake than the victor junior "cathedral" heads version intake.
The LS3 vic jr, is very similar in size/shape to the cathedral heads "super vic" intake.
I'm just trying to help not steer cathedral guys in the wrong direction.... if you want a single plane intake and want it to beat a plastic intake, you need a super vic at a minimum. The "cathedrals" version vic junior is NOT a good intake!
I love the super vic intake on my cam-only 241 cathedral heads 346ci . It rips 1st gear a heap harder than the ls6 intake ever could (i now need to work on car/suspension to get traction back to how it was), it has lost nothing over the ls6 intake anywhere, only gained, and also loves rpm which the LS engine is good at! Best of all worlds

 

My Bad. I don't know why, I thought you had cathedrals. Thought I was defending you. Sorry. I wouldn't change either. What we have found is why we haven't changed from the cathedrals and thats why I still have a brand new CID 5.5 LS7 Fuel injected intake sitting in my shop still in the box. We are using the CID 4.0 version LS3 for a carb. I would talk to John at CID and ask him which version would suit you better. Great guy. Its all about giving the motor all the cfm it wants. He suggested a Accufab throttle body. Our intake will handle a 8500 series with 2.75 throttle bores. We were also going to go with the CID LS7 heads too. Those are some really bad *** heads that no one talks about.

That was my whole point in my other post.. Every time we went bigger it went faster. Think about it. 2 inch spacer and 2 more inches of nitrous plate and burst plate on top of a CID and it picked up every change with a carb just on motor. Every indication these motors want more intake. You can't even tell it has a carb on it much less a Dominator. You would swear its FI if you didn't know. Throttle response is insane from idle up. Drives like a dream on the street too. I can't imagine that yours wouldn't pick up too. Anyway, best of luck to you on whatever you choose.

 

The cid ls7 is a badass casting. Are you going to do anything with that cid intake?

 

We were planning a 427 Dart, LS7 CID heads, and intake, T&D shaft rockers Accufab 8500 throttle body, and a 121 F3 Pro Charger. We would have to go big tire. After seeing the power these AFR's produce all across the RPM, and the way they come out of the hole. We are thinking we may go with a Blow thru C&S on top of what we have. Just got to change the pistons and cam, and add the procharger. Everything else is ready for it. We already have an Aeromotive A3000 fuel pump so fuel wont be a problem. That is one of the problems we have with changing too. We would have to completely change everything to do with the fuel system not to mention the ignition. We have the Aeromotive Pro stock regulators too. With this setup we may go with the F2, top out at 1800HP and stay small tire. With the C&S blow thru, there is no need for an inner cooler so thats a plus. Doing it that way would save us a **** load of money. Decisions, Decisions. Lol

Why, are you interested in buying it? It is a huge intake, so you know. Never thought about selling it. I do have one friend that has been wearing me out to sell it to him since he saw it. But he hasn't asked in quite a while. To be fair, I would have to ask him first.

I do have a Vic Jr, and a Super Victor with a brand new 2 stage NX fogger on it that has never been used. Both for cathedral though. If anyone is interested.

 

That will be a badass motor. I've always been impressed with the AFR castings, too. I remember Lance at Pantera telling me that he always used AFR castings for any of his high end stuff. If you can hook 1800 hp on a small tire, you're a better man than me!

Not right now. I want to see what the 440 does as the build is designed. I joke about not being able to see around the CID, but the truth is i like that my car is still stock interior. It pisses people off on the street. Once you cut it up like that, everyone goes "racecar", and it just isn't as fun, and it's harder to get random nerds to line up on a red light. I am well aware nothing will make the motor run like the CID intake, and it's always sitting out there teasing me. :heavy sigh:

BUT if I end up on the cusp of a number and need a little something to push it over the top, I'd consider it.

 

It will be sitting here waiting for you. Tease, Tease. Thought I had a picture of it. Dam it. Lol

Picture coming soon!!!

 

Lmao!!!

 

Now Darth. Don't drool all of the keyboard, it's not good for your computer. Lol
