I did 1 3/4 headman headers 3 inch collector 3 inch xpipe,got rid of the H pipe, 3 inch 2 chamber flowmasters ended up not liking the magnaflows, also put in a 1/2 inch open phoenolic spacer breaths alot better and climbs the rpm ladder faster,I might have room for a 1 inch spacer that will be the next step,not alot of clearance under the Camaro but today i'll find out if it fits.

Thats why I went with RFI supresiion wires and plugs for 3000kms and 3-1/2 months no noise through the radio,which is a constant noise not the winding rpm type due to rfi suppression or bad grounds this sound is like listening to the distributor firing order throgh a specific sound wave.
This all happened after I changed my cap & rotor and put new hei boots on after custom cutting to length my existing wires , they were way to long from the factory,all parts wereexact as the ones I tossed ,MSD and TAYLOR,. and last I put on a 1/2 inch spacer last weekend and there was a significant difference the car could breath and wind up under load better,last night I switched it and put in a 1 inch spacer ,phoenolic open bore,I only moved the car to park it in the garage but I think I finally woke up the beast .just from pedal feel and sound.althugh i will eventually check it again do spacers in the 1 inch range need the carb rejetted due to the air volume change in the plennum vs before.

Thank YOU EVERYONE who has helped me along the way with my ride.

I changed the contact under the coil and it was all black with carbon on the spring as well the cap and rotor kit came with 2 contacts the [stock] one,and the Msd steel one which I used with dialetic grease,as for the traction issue no I have not adressed it yet, on a daily basis the cars tire will stay as is remember I use it city and hwy on a daily basis thats why I built it to drive it and enjoy it its my little time machine.ive made my tranny decision tremec 5 speed with a .68 overdrive and a 4.10 rear end ratio,i,ll check the ohm readings on the ignition system and let you know, Your right about the 1/2 inch spacer not a huge difference but there was a significant improvement with the 1 inch spacer,

In regards to the resistance for the ignition wires what type of numbers should I be looking for in regards to ohms or any other number. when it comes to electricity that is my weakness I dont understand it very well.

they are Taylor spiro pro's 8mm resisitor type Thanks for the ohm info I will do the redings and get back to you I am assuming the lower the reading the better.
As for the noise its not that winding radio noise its a static crackling sound on battery power there is no noise only when the car is running and its a very low frequency soundit goes through all four speakers but I'm not sure if it goes through the sub i have 2 separate amps I'll get back to you.Thanks again

well I figured out why at times my motor stumbled and momentarily lost power then csme bsck to life I only had a 40 GPH freefflow fuel pump on it rated to 300hp I put a edelbrock performer rpm fuel pump on it which free flows 110 gph and holy crap the motor really came to life before it would pull to 6500 rpm but after 5000 rpm it would take its time now even with the 3:42 gear the car goes to 6500 rpm in a heartbeat ,what a bonehed move I pulled but when I make a mistake i admit it it runs so much better now,I also bypassed the regulator since the pump is preset for 6 psi which is what my ultra 750 calls for,Thanks agaim everyone for all your advice and input.
Now we start to save for a 5 speed.happy cruising everyone

flow

Good for you figuring out the fuel flow problem somethings can really haunt a person.

Again been right where you are at. Been playing with small and big nitrous and going way to fast, for some 30 years on cars like yours and mine . And some silly powerfull racey stuff too.
The Hyd roller cam (limited rpm capability) is a point too with nitrous.
You do not want engine fuel in consistant -leanout or valve float-hyd lifter pump up with N2O. $$$$
Bad things happen fast on nitrous.$$$
You are not there yet.
I totally agree with this...you need to really finish sorting out all the little things naturally aspirated first.

Don't even think about nitrous without an electric fuel pump.

"Bad things happen fast on nitrous" is an understatement for those who don't have all their ducks in a row first. It will happen faster than you can even begin to react to save the engine...literally "the blink of an eye".... and the engine is hurt.

Along with the fuel curve, the ignition timing has to be corrected for the nitrous use.
