Victor jr intake no vacuum port? what to do?

I purchased a Victor Jr Intake to put on my crate 350, plan on building it or another 327 in the near future. Was not aware that there are no vacuum ports on the Victor Jr. ( bought it on a recommendation that I could build into it and it would be best for the future motor. ) Any suggestions on what to do here? Is there a port on the Holley 600 that I can tap into? Bummed....

What do you want the vacuum port for ? Power brakes ? Vacuum advance ? There should be ports on the carburetor's base plate for these. Otherwise you can drill and tap a hole in the plenum and use a fitting like what is shown below.

I had that problem once on a V-Jr. I drilled and tapped a hole on the side below the carb on the passenger's side. Used the port to plug the PCV valve hose into it.

Re: victor jr intake no vacuum port? what to do?

Can you drill and tap at the rear of the manifold?

Never mind, we all had the same suggestion

I got a super victor and added a vacum port at the plug that looks like a freeze plug behind the carb.

Gary,

To be honest with you, unless you are building a pretty stout, high compression, high rpm 350 or a real real stout 327, the Victor Jr is probably way to much intake manifold anyway.

If you really want to use it just drill and tap it for a fitting, it is about a ten minute job.

x2 i will have to agree with Bill here also as i found this out the hard way,i had a vic jr on my 355 which is pretty stout and it was still too much intake vic jr is 3500-8000 rpm.I went with an rpm air gap which works very well with my setup.

Re: victor jr intake no vacuum port? what to do?

lots of great ideas, thanks, pulling the old manifold now, I will have to make a decision soon.. contemplating returning the Vic Jr, but my buddy swears this is a good combo given what I am going toward in the end, he said the car will lose some bottom end but run better on the top and with no slics or huge meats on the rear, too much torque will break em loose anyway.. getting lots of opinions both ways, hopefully I make the right decision.. thanks for all the input.....

Re: victor jr intake no vacuum port? what to do?

he is misinformed
you got a crate engine not a full blown high compression race motor?
ask youself this question.
on the street how long will the car be at or near full throttle to take advantage of the victor JR?
my guess is not too often lol.
for street your better off with a dual plane manifold and youll be happier with the performance and less hassles getting the manifold setup.

Re: victor jr intake no vacuum port? what to do?

Gary,
The Victor Jr worked great on the 355 I had in my 67 Camaro drag car. It was 13.5 to one, huge camshaft, bow tie heads etc. 5.38 gears, around 7800 through the traps. ..........

Point is, unless your engine is an all out type race engine, the Victor Jr is not going to perform as well as a Performer RPM or similar manifold.

Gary,
You dont have to believe any of us strangers Call Edelbrock and tell them what you are doing and what your plans are and ask them which manifold will be the best for you. They want you to be extremely happy with thier product so they will tell you the correct manifold.

Re: victor jr intake no vacuum port? what to do?

ok, so all the opinions are much appreciated, what is your opinion on this? I plan to build a 327/350 with 10.5:1, with power glide, for street only but don't want to get smoked by some stupid 2010 mustang..... my buddy, who knows far more than I do about this stuff says I want the Vic jr with a high stall 4,000 to avoid roastin the tires off the line and gives more hi end (hp) to get er really goin... what are your thoughts on that situation? The video is very telling but kind of supports the torque/HP range opinion??
