well I got my 89 coupe dynoed and yup the number sucked
it was only dynoed at 232rwhp
it has 306 short block
eddelbroke (6025) rpm performer heads with the 2.02 valves
1.6 rr,e-cam,gt40 intake with the bottom fully ported,bbk shorties, bassani x-pipe,2chamber flows,pullies,30#injectors, 75mm MAF, 70mm throddle body,
I was figurering this combo would give me at least 280rwhp
At first I thought maybe I had a burnt valve or may be some bad rings, so when I got home I did a compresion test. this is what I got
piston 1 = 160
2 = 163
3 = 164
4 = 160
5 = 158
6 = 158
7 = 164
8 = 160
so every thing looks good
im thinking my E-cam which is used , may not be enough cam for the heads
what do you guys think, should I go with a higher cam, some thing like a x-cam ? what cam would be good for NOS
on the dynoe the car peak power came at 4500 then it went flat

my e-camed 306, gt40x heads, and holley intake made 290rwhp with a tko behind it, i think u have a bigger problem than the e cam
but maybe not, just my observation is the e cam is good for atmost 300rwhp

Damn!!!, something is definately wrong.....
I have a stock long block (stock~heads & cam) and I hit 255rwhp....
Even with my stock cam and heads my power peaked at 5300rpm.....
What was your air/fuel ratio like?....Do you have a catted X-pipe?...What was your base timming,10*?...

What did your air fuel ratio look like? How did changing timing affect RWHP?

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

No cats, base timing was at 10 then byron put it at 12 but i only gained 2rwhp he said my over all timing was 31
the air fuel ratio was fine according to byron
he also did not now why i was low on power
he said only thing hecouldthink of was maybe a burnt valve . thats why I did the compression test which looks great.
he also said maybe the used E-cam could not be good enough for the heads
hmmmm?

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?

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.

I'd check cam timing, lifter preload, & intake/exhaust restrictions.

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:

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.
