Stock car plugs question ('95 4.6 V8)

Hey whats up everybody,
1st post

I recently got a 95 Tbird. V8 4.6L
I've been running it as a stock car on the dirt track here in town.
The car has a number of issues.

Primarily, the car lacks power after the engine RPMs hit 3000.
I can floor the gas pedal, but won't get much, if any, power after it hits that 3 line. It runs on the track, I got a 4th in the first race with it. This is pretty good considering how badly it ran when I got it (for free).

So I put in some new plugs yesterday (OE design ? whatever that means) I asked the guy at the parts store for hotter plugs than normal.
Now I'm having the same problem, but it happens at 2000 RPMs.

I'm wondering if this problem will go away with a little time, but am a little hesitant to jam the gas pedal in my driveway for too long. I cut off the catalytic converter and exhaust system and the car is really loud (don't want to bother the neighbors).

Do I possibly need to clean the injectors?
Did I obviously mess something up when installing the plugs?

The head honcho of my racing team said to put the old plugs back in and see what happens, but I'd like to get some input before I do that, as every time I get under the hood, there's more of a chance I can screw something up.

Thank you all for your help in advance,
Juice

Re: Stock car plugs question ('95 4.6 V8)

does it miss or just no more power.
If it is a miss it could be plug leads or coil or dirtyy injectors.

If it just runs out of power i would put a new fuel filter on and check air filter aswell.

I think it misses. It just kind of pegs at the specific RPM with no increase as I step on the pedal.

So you don't think I messed anything up with the plugs themselves?
I should mention that I didn't use the torque adapter when installing the plugs.

I guess I'll clean the injectors and go from there.

Thanks again for the timely, and free, mechanical advice.
God I love the internet.

By chance did you replace your spark plug wires?If not i would.
I run standard plugs and gap them at the low end to 50.Gaping calls for 50/55 Wires put out alot of spark and standard wires need replacing from time to time. Good luck

At 3000 RPM i'd say your rev limiter is kicking in.
