up the fuel pressure to what i said...i swaer you will feel a sop difference...expeccially up top..
i cant i have a factory pressure regulator. its non adjustable.

Laser - Those are pretty 'optimistic' numbers that he has lost
67hp?
I was a little overzelous on the weak spark, but still with bent rods and the computer getting bad readings b/c of voltage and a bad sensor
he may be loosing more.

How are the pushrods bent?
The probablem is the P heads have 65cc cambers on them.
My car.
1990 coupe, 5 speed, 3.08 gears,gt40-p heads, b-cam, explorer upper and lower, stock throttle body, stock mass air,stock headers off road x-pipe.
First off now that I am done removing my own hair in clumps. You aint gonna walk a damn UPS truck with no first and second and 3.08's, your lucky you don't get t-boned at intersections. Get some money scrounged up get a set of cheapy shorties, 24 mass and injectors, fix yo tranny and throw in a set of 3.73 or 4.10 and last but not least set your valves right. If you think your car is fast now you'll problably sleep in it afterwards. Bye bye vert. (2.88 gears what are 2.88 gears)
here is the news.. from someone who KNOWS SPEED. he says i more than likely didnt install my rockers properly. i told him i know i didnt install them right. i just bolted them down and ran em. so now i have to take my intake and valve covers off and let him install them the right way. and i am ordering a new HO alternator tonight. and he is going to look at my ACT sensor for me next week. if i am losing 50+ horse power i should deff be able to feel it when he straightens it out for me.
lemme get the enigne first, or well just swap heads lol.

Dude....i really cant believe what im reading right now. I went through this whole thread and no one has ragged on you about the state your car is in.
I hate to be rude but i think you need to spend a little more time researching about whats going on with your car then worrying about how you cant believe you are loosing to this other kid.
Faulty ACT sensor is a huge problem. You need to get this fixed ASAP. If the computer doesnt know the temp of the incoming air...then it has no idea how much fuel to give it.
Next, if you just bolted down your rockers without any idea of what you were doing...you are lucky you didnt really damage something. If you are leaving valves hanging...there is no doubt you are way down on power. This should've been dealt with immediately...especially if they were making a ton of noise.
10 volts is not enough juice for the computer to properly control the ignition and fuel injection. I think there is a minimum voltage limit when the computer starts to use limp mode logic because the injectors cant fire the way they are supposed to. And why would you buy a stock HO alternator. Go to a junk yard and pick up a 3G from any 94+ stang or tbird or many others and upgrade the alternator while you are there...you will wind up paying more for a stock HO alt...and be worse off. The thing was way underpowered from the factory.
Also why cant you get on it above 2k in 2nd gear...this seems like a pretty serious problem too!?!
Sorry for going off on you...but this seems kind of silly. You have a handful or serious problems with the car and you are still out there racing your buddy. Get the thing running right before you break something expensive! (read: bottom end) good luck man
