I've searched victor jr. vs. ls6 intake and found some useful stuff but nothing answered my immediate question and that is which would be more efficient for a na head/cam car with good flowing exhaust.
What are the pros and cons of a victor on a street/strip car??

Unless you have big cubes or plan to spin to 7,500 rpm or more I don't think you will see much gain. If you try to use a 90° elbow you will kill all of the benefits of that intake. It really is designed to work with a 4 BBL throttle body. Also, the single plane intake will want a cam designed specifically for it. I think for just a heads and cam car stick with the LS6 or similar (BBK, Professional Products Typhoon, Holley, FAST, etc.)

I will put in my .02
My car ran stronger overall with an LS6 intake than it does with a ported Vic Jr.
I didn't change the cam like I should have, but with the LS6 the car was an overall performer. When I switched to a Vic Jr, it lost the low end grunt, but pulled really nice up top.
Here is a comparison-- 2 stage 200 shot on a timer
LS6 --------- Vic Jr
60' 1.31 -------- 60' 1.45
1/8 6.38 --------- 1/8 6.40
1/4 10.07 @ 131 -------- 1/4 10.03 @ 133
On motor, the Vic cost me alot. The car was running 11.6 before the swap, and went to 12.0 after. If I had it to do all over again, I think I would get a FAST

so from the research I've gathered, if I'm going to run big cubes, or FI than the Victor can be a more than satisfactory intake, For street drivability I will lose low-end power. So if I can afford it, I'm going to go with a fast intake and if I can't find one on a deal, I'll snag a ls6
Thanks for all the feedback.
