Is it possible to use a victor junior intake with elbow and >100 mm tb on a NA or Nitrous 383? or will it push to much air? I am doin alot of research before i buy and build. i did a search, but not much was found.

it will work! the opening on the tb dont matter its up to the engine if it can move the air.

Id like to know this also. I have a new 383 right now with a LS6, and from what I have read, most will say stick with the ls6/fast combo. Especially if you daily drive it or drive on the street much. Looks like the Vic Jr. seems to work better for the F.I. and BIG cube guys. If others have other results or opinions, I would be all in for listening since mine will just be a high RPM drag car.

I run the Victor JR on a carb setup so i guess my opinion isnt exactly the best but i really love it. The first one i got had the o-rings machined wrong and it cracked but summit sent me a new one the next day and edelbrock sent me free stuff for my problems so it wasnt really bad or anything. They are really designed for rpsm above 3000rpm. I have a very large cam and i can detect cam surge in lower rpms like 1800rpm in high gears (5th and 6th) but i dont know its the cam, carb or intake. I thinks it all of it.

Just for a point of refferent i am running a holley 750 carb and i had to upgrade the stock 30cc accelerator pump to a 50cc pump and from a 25 squirter to a 35 suquirter to get an off idle lean stumble to go away so i know it needs ALOT of air/fuel to get it going

It does help because it still shows the Vic Jr needs alot of air and fuel to it, and that shows how it would act.

I have heard the Vic is better with bigger cubes & larger cam also. I'd say Fast intake on a 347-383ci motor & for a 402+ you'd be fine with the Vic. I have been doin alot of reading on these intakes too.

You will find lots of mixed reviews though, just like most intakes that aren't "cookie cutter". By this I mean not found on damn near every f-body you bump into. I have found from my reading that boosted guys benefit most. But you can still make great power with this intake on say a 408 with good heads & big cam. Thery also seem to be fine in nitrous applications.

I wil be running one on my future combo with the 102* elbow from Edlebrock since it has the correct bolting pattern for a Nick Williams 90mm TB & also has the TB cable bracket provision. I'll probably end up having to get a bigger hood or notch mine though cause I'm also plannin on solid motor mounts.

Vic Jr on a 383 rocks indeed. Everything these guys have said it true. One thing i would add is, it is crucial that the Vic Jr is port matched to your heads. There is a lof of extra material around the port openings in the Vir Jr specifically for porting. If you read the Edelbrock documentation on the Vic Jr, even they say that it is intended to be port matched. When I got mine, the ports were WAY smaller than the ports in my 243 heads. I love mine. Works well with mid sized and big cammed motors. I bought mine because I was afraid of what a small Nitrous backfire does to a FAST. I sold my FAST and more than paid for the Vic Jr and an elbow from Aaron at IntakeElbows.com. I instantly noticed a difference above 5500rpm on my 383. Revs very freely.

It will matter in the tune. Especially if he is going from a 78mm to a 100mm TB, there are some tune changes required to avoid stumbling, stalling and to get a quality idle.

Goldfinger, what kind of times are you running? I have a similar setup to what you have. Well except the intake. I have a new 383 w/Lingenfelter ported LS6 heads. I have a LS6 intake but was thinking of going to the Vic Jr? I just sold my TREX cam, which was pretty close to your camshaft. I will probably go a little bigger on my next one. I was wondering your ET's and HP numbers with your N2O setup. I was planning on running a plate system with a 150-200 shot.

How do you like the victor jr intake?

i havent bought one yet i have been trying to do some research on them to see results first.

Yea same here, A few people on here are running sheetmetal intakes and I was woundering the benefits of those also? here is a vid of a victor jr intake on a 408

But I believe that you can make more hp than that on that engine in the video with a fast 92/92 or a sheetmetal intake. thats just IMO. I have ran a natural aspirated 408 with a fast and produced better numbers than that with heads that are TFS. but I have heard that victor jr intakes are not that good compared to the fast 92's and sheetmetal intakes. thats why i was interested in what people knew on this thread about the victor jr's...

I had a customer with TFS 225's on a 402 and a Fast that ran 10.50's on motor, when he switched to a Vic Jr and a elblow he slowed down.

Guess I should stick to an LS6 intake?
