Think I'm gonna throw the CNCd 799s on it that I already have, and buy a hi-ram and put on it. Then I can put the LS6 intake back on it when i put it in the truck, and re-use the hi-ram on my turbo build for the camaro.

A ls6 intake will take you into the 6s easily. I bet you will slow down with a single plane ,especially in the 1/8 mile because it will be an absolute slug down low. and you will never benefit from the top end in 1/8.I have been 10.70 1/4 , 6.7 1/8 with a ls6 and 243 heads.,

He is correct, don't do a single plane it will loose low end.

Launch

This is a bunch of BS from people who either didn't have a super vic (or better), or didn't have the rest of the set up correct.

Launch

Several "cam only" 6.0 cars with factory square ports heads, have done BETTER et's with single plane than any plastic intake has done with similar set up.

It's all in the set up of the car.

Super Vic lose low end? Who said, a magazine dyno test? I fitted one recently and i'm adding weight at the back to get my traction back to how it was!!!! It has more mid-range than the ls6 intake could ever dream of.

Let alone a bigger CI .... no low end here, just a 1.24 60 ft N/A https://www.yellowbullet.com/threads...o-fyi.2627598/

what does this have to do with a 346 Ls1?

If you can't get into the 6s with a ls6 intake you might want to check your setup.

Honestly who gives a **** what the motor does at 3500 rpm in a drag racing application... it’s never under 5000rpm, so honestly that’s all that matters. **** low end power for a drag car, 5000 rpm n/a converter or 4.56-4.77 rear end gears, by far make up for any lack of low end.

Bspeck82

exactly. This guide has a glide, lots of gear and a 5500 converter and people assume this guy wants to run an ls6 intake. Christ the intake is out of breathe once the converter hits. This guy needs top end power.

Check out Richard Holdener on you tube. He does a lot of head and intake dyno testing for LS.
Check out Snake Eater Performance for a 102mm TB
better than warr. Around the same price. He's ex military too. Helping a brother out by using his products.

I guess not the smartest thing money wise, but I ordered a proflo xt and a custom cam from Ed Curtis, to go with the Wegner CNC 799 heads that I already had. Will re-use the intake on future turbo build, so I’m only out the cost of the cam. We will see how she runs in a few weeks

Post results. when you get them. I ran a Proflo XT and,a Vic JR with a 4150 Accufab.,I kept going back to the LS6.I do have a Fast 102 to put on but I am in the middle of race season..Those short runner intakes lost alot down low but I was not willing to switch cams chasing them. I was down a .1 60ft. The single plane was terrible down low. and I am flashing converter at 5020 rpm. i

absolutely have to swap cams when going from a stock style intake to single plane. Most definitely not worth it if you dont get a cam tailored to the single plane

cam design wasn’t what I expected, I thought it would be a little larger with tighter LSA, but he definitely knows more about cam design than I ever will so we will see how it goes. Hope I don’t lose any 60’

The vic jr cathedral intake is a poor intake from all the results i've seen. It is much too restrictive and nothing like a super vic.

If you don't believe me then go ask Martin that owned tick performance what he thinks about what i just said. He has had customers with cathedral heads gain with the super vic/4150 over even previously running a fast 102/102, let alone ls6.

Launch

Guy comes in here who tried the most **** poor attempt at a single plane intake (which is the cathedral version VIC JR intake).. and thinks he knows it all about intakes.
Edelbrock should have never even made that intake. It has tricked people into thinking single plane intakes on LS dont work. Of course they don't when they try a vic jr which is so restrictive it'd maybe be sufficient for a 305ci with poor heads or something like that.

Swap a super vic onto it, with no restriction above the TB, then come back and tell me you went slower than ls6 intake.

And YOU have been how fast with a Super VIC? The original post asked what intake to get into the 6s.You certainly do not need anything more than an ls6 for that.

Got the cam installed. Haven't fired it up yet.

Is it common for the cam grinder to get the ICL off by 3 degrees? The cam is on a 111 LSA and supposed to have 3 degrees advance ground in. I measured several times and it was coming in on a 111.5-112 ICL. Put a 3 degree adjustment bushing in and it came out to 108.75-109 ICL

Just curious if that is a common occurrence. Never had one off that far I don't think. Glad I degreed it.

Update.

Made 3 passes with the new combo. Driver mod needed as I completely messed up the last 2 passes. First pass was the best. Shift light wasn't working and couldn't log Air/fuel so kinda shot in the dark at tuning.

pass 1 - 5000rpm launch, 28 degrees timing, 1.49 60', 6.89 @ 100 mph
pass 2 - 5200rpm launch, 29 degrees timing from 5200-5500, bad tire shake aborted pass
pass 3 - same launch and timing, tire shake again but not as bad, bumped shifter to high gear right after launch, did i say the driver needs some practice?, throttle cable malfunction, another aborted pass.

All in all I guess I can't complain.
