Can't just look at the cam size & say "oh, those numbers look low for that cam", you gotta take the entire combo into account. And those 4.10's are robbing him of some power.

Look at his other mods though. He is still running stock heads & 4.10 gears out back. Those are solid numbers. I'd bet if he went back to stock 3.42 gears his numbers would have been alot closer to 400.

You are right there. I just think I would have cammed the car for every day use, and then put the nitrous to it. It would have made a lot of power regardless, it would have just been better suited for everyday use. JMO. Then again, Pat G DOES know what he is doing. GL

good numbers dude.. those are close to mine. your cam is bigger but i have the fast90/90. you wont tell 380hp to 400 when you are spraying it..and you better be ready to fill the bottle alot, after you spray once you will be hooked. lol just like me. im glad you got tires. i didnt like those 2.0 60's you had at the track. now you need to launch it had intill the 10bolt brakes. lol its never ending

What's up with the Weiand intake? I thought the stock LS6 was known to be better. Hmm, maybe there's a bit more left in the tune.
I have the same cam and got some nice gains over the stock LS6 cam (LS6 longblock.)

I was looking at your mods and the results and am very interested because I had Patrick G spec a cam for me as well and it is almost identical to yours.
my specs 226/232 609/604 112 +4
So I was very interested in what kind of results you got and was kinda surprised. I figured for sure you would be over or very close to the 400hp/385ft tq range.
Our mods/cars are very similar. I have stock cubes, LS6 intake, ported factory TB, Pacesetters, Moser 12-bolt with 3.73's, Spec Stage 3 clutch (aluminum flywheel) with a set of 241's, and a very small MTI B1 cam 221/221 558/558 114. The 241's were stage 2 ported by Cartek. With this combo I put 416 to the wheels. Prior to the headwork I put the 385/365 to the wheels, no other changes.
My cam is pretty small, the heads do flow better than stock, but could they be worth as much as 40 hp? If so what would the cam be worth? Any ideas? Maybe the torque curve would be flatter?
I think there is some good power left in your combo or my understanding of engine dynamics is not up to par (very good possibility).
Good Luck
Chris

The cam is a great cam, I have the same cam on a 111+1 and love the overall power under curve. I have a LS6 intake, stock 98 head and some beat up old hooker LT's and put down the numbers in my sig. My heads and headers are holding me back a bit. The vette's typically put down better numbers due to the better designed exhaust, its not somethign that is foreign to F-body's, we just needto spend more time making a better y-pipe or spending big bucks, this is one reason why Ryan's numbers are so nice. If I were to do a cam right now, I would have eithe rwent with my same cam or gotten somthing a bit bigger on a LSR lobe, but then again, I dont drive my car everyday and I do like to race it when I get the opportunity to do so. I would have to say you would be looking at 42x/39x on the same dyno in the same condition, ofcourse the advantage would be better with a better Intake and T/B.
I think the OP's gains are solid for the mods. There are alot of little things that could be done to help out but overall with his mods and those numbers, then car should run like a beast.
1qwikbird - I dont see you gaining much peak over what you have now, but I do think that you would ahve better area under curve.

My weiand intake should be at or above a ls6 intake. I'm pretty sure it has the ls6 intake design and plus it is ported. With my stock clutch I would have made more. I added the ls7 clutch and did the drill mod so it could handle the power with no sticking. I think 45+ HP and 40-50 more TQ at 6k rpms is great. Overall i'm very happy with these na numbers. This was not meant to be a na cam

Which is what some are missing on this build. I think your numbers are right on. Just go to the track & let the ET do the talkin man. Some people forget dynos can vary between shops, elevation & humidity can also effect your numbers. People also forget the dyno is mainly a tuning tool. The numbers it puts out really aren't important unless you just want to brag about your numbers. Personally I'd rather brag about ET numbers than dyno numbers.

I think the main problem with that intake is the heat soak. I have seen people with ported weiand intakes, swap over to LS6 intake and gain not only peak, but across the whole board as well. Antoehr down fall to that intake is how much weight you add to the motor. People will typically run this intake if they are sparying alot of nitrous, or putting alot of boost through the motor. The only way to tell the difference though would be to out the car on the same dyno with a LS6 intake in the same conditions and overlay the graphs. DO you konw wha tthe intake air temps were on your pulls?

Agreed you usally see more people with big nitrous or boosted set-ups running it b/c of it's added strength. But I believe more people dont run it b/c the eariler versions had sealing problems, false theories about heat soak (aka heat soak fear, LOL) & cost.
Normally a Weiand cost more than a LS6 right off the shelf & the LS6 will out perform it but if you can pick up a Weiand thats already ported for the price of a LS6, then I'd go Weiand for it's growth potiential over the LS6.
