i'd be interested in more info.

This is a NOS Cheater plate system (150-250hp). It has a 1/2" nitrous/fuel plate on the front & rear carb. The center car has just a 1/2" spacer, but it does have the holes drilled to add nitrous/fuel spray bars, so I guess I could add a 2nd stage if I want to. I'm running a Holley Blue fuel pump & I've already run a second 3/8" fuel line for a second Holley blue fuel pump to supply the nitrous system (currently tapped into the single fuel line). I'm running 6psi fuel pressure now, but will probably turn that up to 6.5psi.

Because the carbs move up 1/2" with the nitrous/fuel plates (& 1/2" blank spacer for center carb) the choke thermostat becomes 1/2" too short. A buddy of mine welded a piece of metal coat hanger onto the choke and I plan on bending & cutting this "custom 1/2" extension" tonight (I'll try to post some pics). The nitrous trigger button I bought at Radio Shack for $3. It is mounted inside the left 1/2 of the pistol grip handle... now the pistol has a real trigger.

The other possible issue is the idle screw on the center carb (over the electric fast idle solenoid), but the screw is pretty long, so it looks like I don't need any modification. The slight change in angle for the throttle cable is easily fixed with a cable re-adjustment.

I've never run this much nitrous, so it's gonna be a hell of a ride!

The engine is balance and has forged TRW pistons/six pack rods, 1/2" Hemi oil pickup tube, FelPro head gaskets, Comp Cams 488/491 274/286 hydraulic cam with DC double valve springs, PC valve stem seals & Isky pushrods/rockers. The outer carbs have short yellow springs & stock metering plates and the center carb has a 3.5 power valve & #66 jets which seem a little rich.

I plan on running a 5-7 degree timing retard when the nitrous is activated. I've got a MSD multi-stage timing retard box but it's not wired in yet. I also plan on installing a line lock (roll control) and running that through the two step rev limiter so I can hold the car at the line floored at 2800-3000 rpm or so, leave by letting off the line lock and letting the clutch out and then not hitting the nitrous until the top of 2nd gear (or 3rd if I can't get traction in 2nd). The car has 3800 super stock springs and street tires, so traction is a problem for sure.

Same system as mine. I ran it on a 440 powered '67 Cuda. Was good for .50 seconds. Had it setup to engage in second and high gear only.
Been sitting on the shelf for years now.

I just re-intalled the nitrous system (NOS Cheater) on my 1970 Road Runner 440 six pack & I thought everyone might like to see some pics. Enjoy!

cool I just got a my box last night let me know how it runs.

why doesnt the center carb get sprayed ?

---

in my case because that's were the Meth/H20 fogger is I'm going to TRY and run the NO2 off the same circut as the Meth/water. I switch it on and when I go WOT the pump pushes the mixture. It works off vacuum when it goes to zero the solenoid opens.

OP do you have a diagram of the set-up???

Looks cool. I have been wanting to ad to my sixpack car for quite awhile now. Only thing that has stopped me has been hood clearance issue on my Charger. I don't want to change from the factory hood. The sixpack air cleaner already rubs the hood pad.
It is hard to find the nitrous kit since discontinued from Holley.

get one of these and you'll have no clearance issues...
