Cam only, low numbers??
I think he was referring to the lift on the cam and how it is pointless to have a cam with that much lift and heads that won't even come close to flowing what the cam would like to have. I see his point though, bottlenecking flow in the heads sure isn't going to help anything. Yea man you really need an ls6 intake at the least.
I think the OP should leave the cam he has.
The next mods i would do would be:
LS6 Intake (~$300)
Heads (TSP sells the PRC 5.3 S2.5 heads for $1100 right now... best bang for the buck out there)
The cam isn't to big, it's either in the tune, or in the install. How many miles are on this motor? It may be just a lil worn out.
For anyone saying the cam is to big, go have a look at the cam only fastest list

. Guys Im not completely sure if the converter was locked on the pulls but I will find out as I need to go there next week to get a few things worked out.
Work on the car is done for the rest of the year unfortunatly as 1. NO money...you all understand that one! an 2. I go back to school in AZ in a week so modding the car will go on the backburner till I find a job out there.
Next summer the car is getting a complete look over as well as me an the guys who do the work on the car have decided we're pulling this cam for a LG G5x4 cam and throwing a 200 shot at it. The car will also most likely go to speed inc. to see if their tuning is better since I have a friend there and at some point like stated above the car will see PRC 5.3 heads. Were thinking cam only with the 200 we should see low 11's to high 10's....which will def satisfy me after this summers dissapoinments

To the OP, I hate to see you give up on a cam so quick, but I can understand. Definitely put an ls6 intake on top of your list. It's more than worth the money with your mods.

definately needs the ls6 intake for sure. i just had my car tuned and my numbers and mods are in my sig. i havent had it at the track yet but im anxious to see what kind of times it puts down with my setup.
you said 350 on a mustang dyno right ?
dont they dyno about 12-15% less then a dyno jet?
so on a dyno jet you would put down around ~390 which isnt bad.
alot of guys just spiting out thier numbers in this thread but every dyno is diffrent, hell even some dynojets out there are stingy...

You cant lock the converter on a wide open pull unless its A. designed for that B. you are willing to tear the clutch up and spit the **** all through your transmission. 
yall keep asking him questions about the converter and whether the cam was degreed and **** like that and he dont know. If he dont know what a cam being off a tooth means then maybe he should turn the whole thing over to a professional and let them figure it out.

Those are not horrible numbers for a cam only a4 on a mustang dyno! If you put 354whp down on a mustang dyno, thats more like 375-380whp on a dynojet. Seems par to me IDK....
*Fwiw a t-rex cam only 04 gto, m6, only put down 352 on epp's mustang dyno a while back.

Really?
If I'm spending the money on dyno time you can damn sure bet mines gonna be locked! Not on at the track but on rollers looking for
horsepower #'s you better believe it! Last edited by MPFD; Aug 18, 2009 at 04:49 PM.

If you don't lock the converter when running it why put it on the dyno locked? Just for a number that makes you feel all warm and fuzzy inside? Your truck goes down the track with the converter unlocked. Dynos are tuning tools, not bragging tools. Therefore you should dyno with the converter unlocked for tuning purposes.
And 355rwhp on a Mustang dyno with that converter unlocked and the LS1 intake is right around where it should be. 108 traps are terrible, and the 111 traps are a little better, but still not quite what they should be. Put an LS6 intake on it and wait until some cooler fall weather and if the traps don't improve to 114-116 or so, then start looking for problems.

I agree that he is about on par. But everyone one this site is only worried about peak HP numbers and that what people continue to write threads
about.
