Help with a new thing
Hey guys, something new to me and I was hoping that some of you guru types could lend me a hand. I've just purchased a Vic Junior from a forum member and was wondering if I should use it on the Vette. Currently I have an LT4 ported intake but lots of folks seem to think this is a better way to go.
What would I expect to see with this vs the LT4. Wider powerband, better top end, or should I just resell it. What are the pro's and con's of this setup. It's going to be going on a solid roller 383 that's well built and I expect to rev to around 7000 RPM. Some of what I've read seems to indicate that there is extra horsepower and a wider powerband with this setup but I dunno. Others say it's a waste. You all know how Google works.
Also, it's 3" taller than the LT4 manifold and I'm going to guess that it won't fit under the hood. Does anyone have a recommendation for a scoop/cowl something that wouldn't look too nutty. I'm not really into the crazy, radical look and I just want 3 more inches. (Not the personal problem 3")
I just want something really trick looking and now's the time because I'm painting the car this winter. Thanks. ---Gunny---

For the extra hood clearance, I would look into a Toledo Pro hood. They look awesome, but I think they are a bit pricey. If you have the money though, that is the way I would go. They are $1400 for the "high-rise" version which i am assuming you would need. From their website, Hi-Rise hoods are 2 3/4" rise and fully functional cowl induction. Super Hi-Rise is another 100 dollars, but is a 4" rise.

Looks like that is a PN 29785.... which would be the old Victor E intake with provisions for injectors straight from Edelbrock. You look to have the PN 3847 TB adapter.
Those together should measure about 8.5" tall but that big boss cast on top of the TB may make it higher..... With minimal work on that boss it should fit under the STOCK hood fine.
It's a very good intake for somethig like you are building.
It will crush an LTX intake from about 3000RPM up to whatever you wanted to turn it.
I have a PN 2925 Super Victor thats converted for use on my 92. Engine specs are in my profile. As you can see nothing crazy. Pump gas, stock computer, even has a hyd cam in it....
Look at the Single Plane intake this way.
1. The intake runners are twice as long as the LTX (awesome midrange TQ).
2. The runners have a way bigger cross section (no top end restriction).
3. The plenum area with the TB adapter is smaller - about 3/4 as much (higher air speed=more responsive to throttle input).
4. Single plan intakes have the best air distribution because they feed all 8 cyls from a centeral plenum (no lean rear cyls).
Hood Clearance wise you can have an intake that total height is 9" from the top of the block china rail to the top of the TB.... Thats in the front. Thats where the hood starts to slope down and where it's the closest. In the rear you have 1/4 to 1" more depending on where you meaure.
Obviously the intake/cyl head bolt patterens between GEN I and LTX are different. Learn from my mistakes here.... Drill the GEN I pattern into your LT4 cyl heads. We welded up my intake and drilled it to the LTX pattern.... way harder to get everything lined up right and then your stuck with very limited (port size wise) intake gasket choices.
You'll need a few adapter fittings for the fuel lines. You plumb them in down by the filter on the passanger side frame rail. I have the PN's and can give them to you if you want. Of course your going to need some -6 AN fittings and lines for the fuel rails.
The throttle cable should be long enough to cross over to the passanger side. Mine has lots of room to be moved around.
Thats about it. I'd really like to see more people get aboard the single plane intake train.... I'll let my 92's performance do the rest of the talking.
11.17@127.4 mph with a (extra crappy) 1.78 60ft.
That is with a 6spd on 17" radial tires, not power shifting and the car is raced just as I drive it on the street.... The computer is close on the tune but not near perfect yet. Full Corsa exhaust in place, AC, crusie, STOCK FX3 suspension and all power options still work.
We recently drove the car over 400 miles round trip to Carlisle and home (yes in the hurricane). It averaged 19.4mpg for the entire trip and 23mpg on the hwy. This year alone, I have put over 7000 miles on the car and now have over 40 passes at the track.

Seriously, if you think the TP hoods are pricey, check on the cost of a GM replacement hood!
When I got mine, it was $1100. (They are kinda like the FIRST intakes and EM Headers where they'll really sell for less if you just ask!) GM hoods were $1600 back then. Probably higher now -- if you can even get one.I like the Greenwood hi-rise scoop for people who don't want a whole hood.
Vanacor's used to have a really nice high-rise piece too, but they "tanked" after Katrina. And, it had nothing to do with water!

The Edelbrock TB adapter you have, didn't come out until 2yrs after I had built my stuff. When I did mine there were only a few people with single plane intakes on L98 cars and no one had done it for an LTX except a very dedicated F Body drag racer (Joe Overton)....
I so wish that TB adapter was availiable when I built my car. The LSX Tb's are so much easier and cheaper to buy than the TPI/LTX TB's....
I've got so much hand fabricated work in my setup.... and now you can buy better or just as good of stuff right from Edelbrock.
I don't know everything (first hand) about the parts you have but I have looked in to it and done alot of research for other people. You have the Intake manifold and TB/TB Adapter that I figured with a little work, would work just as good as my hand built deal.
My measurements on those parts came from Edelbrocks listing for the intake (4.58") and TB adapter (3.62"). If you could get a tape out and meaure it's over all height - I'd like to see how close reality is.
With the stock hood alot depends on how far forward the TB is located. Mine is mounted in (pics anyway) what appears to be close to the same location relitive to the front of the manifold, but if yours is 1" or 2" further forward it could mean it'll hit.
If I can help further let me know.
I have lots of pics of mine and could take more with a tape measure set up next to it.

Sweet intake. It may fit, Will is on the right track to measure and determine if it will. If it doesn't you could take a page out of Anesthes book. He ran a supercharged single plane and ran the snorkle and TB 90* towards the driver's side. If you're willing to run a cone filter or put in some piping there is no reason why this wouldn't work for you if it ends up not having the clearance to run it forward.

Oh, BTW thanks guys on the suggestion for the Toledo Pro hood. It is a little expensive but man it's sweet.Hmmmm, since I'm not married there is no one to bit** at me if I get one.
That may be the way to go....we'll see.

Semper Fi Gunny,
I think that Toledo Pro would look awesome, because it's pretty mild,
and keeps your car looking just that lil more bad-*** over the stocker..
I used to have a 1969 coupe that had the Motion Performance style hood on it..the big hump and chamfered corners..like the LT1 hood on steroids, I loved being behind it..it just looked tough from the drivers seat and in profile, even though I had a wimpy small block in it..good luck with your build!
Derek.. "Doc", 2nd/4th 3rd Mar. Senior Corpsman lejuene, pendle, stumps, fuji, oki, subic, ologapo, cubi point, atusugi, yokohama, yokosuka, west pac..floats, Uss Tarawa LHA1 and Uss Jeauneau, LPD 10 as my old man said. "corvette? what the hell did you buy that for, I never saw one on a tin-can!"

A few pics of mine.
8 1/4" tall - measured from the china rail on the block to the top of the TB.
16" long - measured from the rear carb flange bolt to the end of the TB.
