What was your air/fuel ratio like?....Do you have a catted X-pipe?...What was your base timming,10*?...

I thought you had an E cam?

well if I do have a bigger problem
I dont now where to start looking right now

maybe a change in spark plug wires, and coil
I dont now how old they are but when I bought my car they came with it.
But I think im goin to swap out the cam.
with a TFS 2

the motor runs really nice and smooth.
idle's great, and when I get on it it responds great,The only bad thing is im runing stock gears 273 so it takes alittle longer to rev

I was so pissed I did not even ask them for one
I figured what the hell is the point
all I now is it went flat at 4500rpm
but the air fuel was good up to 5200rpm's

well that's your problem (flat after 4500 RPM)..... is the throttle body not opening up all the way? Exhaust restricted some how?

thats what i was talkin to your brother about before we left javi, but he said you guys checked and it was opening all the way.......hmmm, hope you get it fixed soon

Riceboy shop dyno reads 15-20 rwhp high then

Maybe your cam was installed wrong?...Did you degree your cam?...If you have too much lifter-preload you open the valve's a lot longer, giving you a lower power-band also...How is your idle?....

If these seem like stupid questions, I'm just "brain-storming"...

I couldnt help notice that you said you have a used e-cam. WHere did you get it from and are you sure it is a real E-cam or since you are flatening out at 4500 it might be a stock cam with a e-stamped on it by the seller i have seen this alot in the used cam 5.0 market with stock cams being labeled with the e,f and x cam designation. As for the rumor about a e cam maxing at 300 hp i think that is a bunch of crap i have personally seen a 306 with ported tfs wedge heads extrude honed gt40 lower and downs upper and a e cam hit the rollers at 353 rwhp in socal.

Posted by jayl (Member # 185) on :
 
i dont know if thats fake or not, but that cam lobes hella hard..........definitely not stock!

Posted by BOUNTY HUNTER VERT (Member # 2754) on :
 
The only other thing i can think of is the cam timing.
 

---

Posted by 93PONY (Member # 60) on :
 
I'd check cam timing, lifter preload, & intake/exhaust restrictions.

how is the block?

Posted by st5150 (Member # 51) on :
 
Even if he got a stock 5.O cam, it will peak at almost 5K RPM, not 4500. Here is my stock motored AOD car with only underdrive pullies and 3 chamber flowmasters with 160,000 miles on the clock:


 

---

Posted by 99gt-UJSTLST (Member # 584) on :
 
the block is just rebuilt
it has only 1000 miles on it

well I can only think of the cam being the issue here, it was used. It cam out of a motor that trew a rod. It was hard to take it out. Maybe it got bent or something.

I thought about cam timing but I now I lined it up I double checked that.

well Im goin to go with a TFS stage 2 cam
my eddlebroke heads can take a 557 lift

im also goin to change my coil and plug wires\
just for good mesure

Hey JAYL I got the NOS goin
the damm fuel bit was pluged up

Are you 100% sure you have an E-cam? Going flat at 4500rpm sounds like a truck (F150 or Explorer) cam.

I don't know if this is a stretch, but if you want it fixed for real, call Jon M. or Brian (thebrain), both professional wrenches.

Otherwise we can guess at you a few hundred times until you find it yourself

one thing to check is that you're firing on all 8, drop some water on all the header primaries while it's running, see what you get.

im sure its torn down by now, javi doesnt seem to waste anytime! and i dont see how a stock cam could sound even close to this beastly shit!!! sounds like a solid roller car i know of! lol

LOL not torn down yeat need it to get me to work
THE NOS DOES WORKS KNOW

but my new tfs2 is on the way along with a new coil and wires

it has to be the cam thats all I can say
Im no master mechanic but the car runs great Idles Nice, does not miss, when you get on it, it responds. It does not feel that fast but with 273gears in the back it takes long to REV up. That will change on wedsday, the 373 gears are goin in

Well thanks for the help
Ill let you guys now how it turns out once I redyno it with the new cam
