Just trying to get things buttoned up on my car. Carb is a Holley Street Avenger 670cfm elec. choke; brand new. Throttle bracket is an AED w/Lokar SS throttle cable. Car has Nitrous Works 1/2" Nitrous Plate, several heat sink spacers/gaskets, and also a Wilson Pro-Flow Nitrous Manifold. I have a 14" K&N Filter w/the drop hat under it (to clear my hood). I've got long studs coming out of the intake for the carb (ARP if I remember correctly).

I'm having a problem with the fitment/alignment on these items. Carb w/spacers & nitrous plate kit & manifold does not sit high enough on the carb studs to be fastened tight (threads are still too high; far away; from the carb).

When I set the air cleaner onto the carb, the air cleaner hits the solenoids for the nitrous/fuel. Also the AED bracket hits the solenoids...

Ideas, suggestions, fixes?????

 

I'm thinking I may need like a 1/2" to 1" carb spacer...

I also need one of these (mine's missing) :

 

josh i got a 4 hole/open spacer you can have....

 

Johnny boy, how big is that thing? Any idea if you have any of the throttle bracket balls? I'm also thinking I may need to figure something else out for the routing/mounting of my solenoids/etc for the nitrous kit. With this Wilsons Manifold thing, the solenoids hit everything; anyway I turn it (upside down, backwards, forwards, lol)........

 

Ill check tommorow on size of spacer

 

Here's some visual aids in the issues that I am trying to overcome:

I've tried the Nitrous Manifold in different spots: at the base of the stack, closest to the intake; at the top of the stack, closest to the carb; upside down, backwards, backwards and upside down - the way I thought it was supposed to go was at the lowest spot, closest to the intake. This worked "best" - but the throttle linkage (on the carb itself) hits the braces on the nitrous manifold. Then the AED throttle linkage actually won't fit down onto the carb studs, because the nitrous solenoid is too tall. Even then, it (the whole shebang) is still too far away from the threads on the carb studs to be fastened....

See:

Nitrous Manifold at top of stack, just before carb:


Linkage from the Carb is actually hitting the Nitrous Manifold's bracing, so you can't even mount the Carb...


Closer view...


Mounting the N/M upside down (saw this on a few cars at NMRA), but it puts the solenoids down ontop of the valve covers (hits)...


See, it hits...


Now installing the N/M on the bottom (which is what I thought was "supposed" to be correct)...


But the Carb linkage STILL hits the brace (this time, just barely)...


Still hitting it at full throttle...


Here's the issue with the AED Bracket not setting down onto the carb studs (due to it hitting the nitrous solenoid)...


And a good shot at how far away from the "threaded" portion of the carb studs we are...

 

Oh, and that doesn't include any of the fitment issues with the throttle linkage, air cleaner (w/drop hat) or the hood......

 

flip the nitrous plate over, and then flip the solonoids to the other side of the plate?

but why use the plate? i just have my solonoids connected to the spray plate with hard lines. that supports the noids just fine.

also you need shorter carb studs.

i had problem with my Moroso drop base air cleaner. it would hit the float adjustment screws for the fuel bowls. i had to use a 1/2" air cleaner spacer. i got them from auto zone. they are little ABS plastic rings that move the air cleaner up and lets it clear every thing

 

Ok...Josh....Here is my idea...BEND the nitrous bracket down just a bit on the throttle side.....Just enough to clear the throttle. Since it's aluminum, you'll have to use washers to hold it down as well as the other spacers you currently have on there. Also, I would use shorter studs. Call me if I don't make sense.

 

I'd contemplated bending the nitrous manifold on the driver's side (throttle bracket side); that would resolve the solenoid hitting the throttle bracket - but still wouldn't solve the carb stud situation.

To resolve the carb stud situation I was considering running a 1" spacer, instead of the half inch worth of heat sinks/gaskets that I currently have. That would give me a full hafl inch more, and put me right at the bottom of the threads on the carb studs.

My issue with the throttle setup on the carb, is I wonder if I can cut that bottom portion off, or if they sell one that is for more of a "race" application than a "street" application. From what I can gather, the linkage has a bunch of stuff on the bottom of it for where maybe a "kickdown" linkage/spring would go on an otherwise stock auto car?! And that seems to be the section that is hitting the n/m brace.

And I'd thought of looking into the air cleaner spacer...
