I have an 84 camaro with a 5.7 swap in it. I bought a victor jr. intake and a 600 performer carb... had someone on here tell me the victor jr. would make it a pig and the 600 was a waste of performance money.... while the mechanic we use through my work has the nickname rain man cuz hes magical with cars.... he said the vic jr. intake would be fine and the carb would be a huge inprovement over my q-jet which is always bogging as it is and leaks fuel( had it rebuilt 3 times.. still junk) my dad also uses the 600 but with just a performer intake on his 350, so far he is very happy. so my question is... is my mechanic full of bs and it will be a terrible choice of intake or would it be fine. sorry for long post

 

vic jr makes power up high, u should have got a dual plane intake if its a street car, A performer RPM AIRGAP is a good comprimise between up high power and low end torque needed on the street. and if ur QJet was malfunctioning then yes the 600 is an improvement, but if the qjet was to work right it would be better then the 600 edelbrock.....5.7kid will probably chime in on this i think he gets an alert everytime a QJET is mentioned lol....listen good to any advice he gives.......even if it contradicts whay ive said lol........

 

Get a dual plane. Victor intakes are for race engines (high rpm).

A 600 Performer isn't much better than a Qjet unless the Qjet is worn out. I think the best SBC Qjet is only 650 CFM. A better choice would have been a 750 CFM carb and for your application, on any dual plane intake.

 

alright so i guess i would be returning it but now... im sure i will hear the differences in opinions on which performer intake? lol... rpm, air gap, reg performer... and i chose 600 because i didn't wanna have more fuel than needed.

 

Go with the Performer RPM, it can be worth 20-30hp and have the same torque output as with the Performer.

so the the performer rpm or would the performer eps be best... it is a street car but i drive the **** out of it. wish it was a nascar....

 

Go with the RPM, air gap if you wish. The RPM line is one of the best street intakes on the market, in my opinion.

And for the record, NASCAR-esque SB2s are a PITA to drive on the street.

 

Go for a weiand stealth or air strike. There just as good if not better than the edelcrap and there better priced.

 

3rd gen q-jets are capable of flowing 750+ CFM. Some need to have the secondary AV tab modified to allow it to fully open, but that's described in the q-jet tech article.

Which intake is correct is a question of use and the overall combo. Very little was said in the original thread about details such as cam, heads, exhaust, converter stall, or intended use. Regardless, a Victor Jr. is rarely the "right" manifold for a street engine - for one thing, you need at least 4000 RPM stall to get it into the powerband off the line. The Performer RPM is better than a Performer or Action + when the cam powerband goes above at least 5000 RPMs. The one advantage of the RPM over other brands of dual planes with similar powerband is the availability of a spreadbore version.

It's hard to imagine an engine that would be "right" with a Victor Jr. and 600 CFM carb.

I don't necessarily "jump in" every time a q-jet is mentioned, just when misinformation or wrong-headed things are being said. Of course, that means I "jump in" to almost every thread when a q-jet is mentioned. . . If the q-jet "is always bogging as it is and leaks fuel( had it rebuilt 3 times.. still junk)", it has been worked on by someone who doesn't know what they're doing - the sad part about that is the poor q-jets are often left FUBAR when worked on by someone who doesn't know what they're doing. One is immediately suspicious if the person working on the q-jet is the same one selling the Performer and thinks the Performer is superior to the q-jet. Bogging is a very simple thing to fix (also documented in the q-jet tech article), and if the person working on it can't "fix" that, I rest my case.

(And, for the record, I was the one who said the Vic Jr. would make the engine a pig, and recommended against the Performer carb.)

 

yes you was, I wasn't calling out names though, i have nothing against you, and the reason i feel the carb is the problem and not necessarily the mechanic is because it has been rebuilt by 3 different mechanics none of which have done it justice, whether or not its the mechanics or the carb i do not know, as for engine details it is a gm 350 crate motor, i have not had the time or money to make it a beast so it is stock, im a college student that works full time and lives on my own so money and time is rare. That said i am wanting to upgrade the intake and carb for noticeable improvements, and do some exhaust work to make it sound good but also enhance that performance, so what i would like to know is would the performer rpm intake be too much as well? and also do you know someplace in oklahoma that can make the q'jet run right? or is there a carb that would work with the intake that is up to par for your standards. I am a rookie so im listening. the motor was fitted with the pulleys and intake and exhaust from the original 305, as for the carb it operates decent when it is cold but as it heats up things get bad, when shifting into second the front end drops as if it lost power but picks back up after a second or so and about halfway through second gear, if it is still full throttle it will start cutting out but if i back off the throttle about a 1/4" while its doing that it picks up and charges like it perfect, but its not at full throttle still, also cuts out when taking off occasionally. Has been doing this since before the first rebuild and hasn't gotten better.

 

I dont know if Im stepping over boundries here or not but a member here that goes by the name of "Jamon8" is selling rebuilt Q-Jets in the market place here. If Im not mistaken the prices were pretty darn good and I think that he can also modify them. Just throwin out an option

 

its crazy how i hear so many people around me say get and edelbrock and loose the q-jet but on here its complete opposite how is one suppose to know what to do. is it all personal preference or can anyone prove ones better... im lost... also which intake would be good with my stock 350, i will be doing exhaust at same time or right after but the cam and heads will have to wait.

If your going to be on the street most of your time, go with the EPS manifold, it will make more low end, which is what your looking for. As far as a carb goes, its all prefrence. But I would atleast go with a 650. James

EDIT: Which crate motor do you have?

your leaky fuel prob might be a bad float, when they get old they lose their bouyancy(they stop floating) I had that prob before I swaped to a holley, I have nothing against a Q-jet, I just hate trying to get the metering rods in right! as for the intake, I would go ith the performaer eps. I had one and it worked great, way better than the stock Iron hulk, but not to much for the old 305!

good luck-

A Victor Jr. is absolutely the wrong intake for that engine.

A Performer carb might run better than a jacked-up q-jet, but it will never outrun a properly operating q-jet.

Primary metering rods aren't a problem with a CC q-jet. The secondary rods are no harder to change than the rods on a Performer carb.

 

Yes, that intake is the wrong one for that application. That would be like putting headers with 1.5" tubes and 4" collector on a V6 and mounting them to stock exhaust.

I personally would go with the RPM in this application for a daily driver.

Edelbroke carbs are easier because most people have experience with them. People always seem to assume that stock parts are junk and substitute perfectly capable parts for ones that may have less potential. Edelbrokes are generally cheaper then Hollys so that is what most people go with at first.

I had someone that knows what they are doing help me with the Q-Jet on my Vette. Wanting to keep it stock I strayed from the stock is crap mentality. Way more responsive and pulls through the RPM range better then my Nova that I put an Edelbroke on (I think 600cfm. Can't remember).

 

I was looking at that motor last night, nice all around motor, but I think after you get your intake all sqaured away, you should look into a nice cam, the cam in that is really small for a 350. After, carb, intake, and cam you should notice a nice little increase in power if all matched correctly.

 

THAT I'd agree with. Plus, they look nice and shiny so they must be good, right?

The engine was intended for the van fleet replacement market. You know, the repair trucks that get abused by employees that couldn't care less because it doesn't belong to them. It has poor-flowing heads that don't support much more cam, and dished pistons that put compression in the mud. They offer a 290 horse version that has a better cam, but that's about the most you can expect out of it.

And, you shouldn't pick any parts until you have your whole package decided. I don't agree that the RPM would be a good intake for this engine.

 

i know the victor is bad now,, its returned out of the question completely.... no more discussion on that... i would agree the heads will be changed after i get more money, five 7 you said the rpm would be bad but what bout the eps? i have had 2 people say that one so far on here

 

what you really need to do is figure out what you want out of your engine. throwing parts on an engine without an idea of what your looking for doesnt really help.. i have a rpm air gap with a holley 670 cfm im happy with my setup but i also know im going to be putting heads and a cam on the motor .. which will really make the intake perform best.. an air gap is really designed for more horse power and aluminum heads.. any setup can work great if its tuned right and used with other parts designed for it. what you really need to ask yourself is how your gonna drive it.. daily driver thats quick but doesnt kill you on gas. a holley 600 and an rpm is a good choice and youll get a good response.. now if your gonna be going for a 12.5 street car. i would look into a 670 cfm. and an air gap.. look into a nice set of heads.. because thats where all the power really is..

do some research.. theres plenty of info out there

 

yea, im wanting a daily that i can have fun drivin everyday and if i get into a race im not tellin myself theres no chance, i love to cruise and i do some street racing occasionally. like showing them hondas up. In the future when i have another car i would love to turn it into a stroker, but for now i want a quick and fast street car that i can enjoy drivin, im not real worried about gas mileage too much but i don't want a dragster to drive to work every day either, im mainly looking to get some more horses out of it without doing major internals for now. I was looking at an intake, carb, headers and back exhaust. all real soon so im trying to figure out the right combination, when i get more money possibly heads, but for now i wanna build it as is into just a slight-to mild modified 350.

 

your on the same page as me.. i got the 670 cfm holley and the rpm air gap.. works good for me.. i know im doin more work soon too so its nice to know i can still use the intake with some new heads and a mild cam.. winter is a little rough on the car with the air gap.. but i just gotta let it warm up for a good 10 15 mins.. but it runs like a top.. good luck with yours
