Another Hood Clearance Question

[john108]

I have seen this question raised many times but always with slightly different components.
1968 Charger with a 440 engine.

From what I understand, a Performer RPM # 7193 inlet manifold will fit with the K&N 66-3040
Air Cleaner Assy- 14 inch Drop 1.25 on top of a proform 950 carb.

But if you replace the RPM manifold with a Holley Street Dominator #300-14 manifold
AND 1 inch insulator under the Proform Carb.  What does this do to the clearance.

Does anybody have this configuration?

I tried to gather the data, shown below, for the two inlet manifolds.
The street dominator appears to be .66 inch shorter than the RPM manifold.
Does this leave room for the 1 inch thich phenolic spacer?

Does the 14" Air Cleaner cause any other concern?

                       A Dimension-Mean Height- B Dimension   Notes
                  
Performer RPM # 7193       4.90   5.35   5.80   1.7 Inches Taller Than Stock
                  
Holley Street Dominator #300-14   4.13   4.69   5.25      
                  
Performer - Holley Difference      0.77   0.66   0.55

I can't guarantee you anything when it comes to hood clearances... I will tell you this much though, on my '69 I had with 440, I ran the Holley Street Dominator intake with a Demon 750 carb, 1" spacer, and a 14"x3' chrome air filter assembly with drop base, I managed to put a standard depth socket on top of this air cleaner, lined it with the sockets, managed to close the hood without any contact....

Hot_Rodder - does your Carb have a choke?
Is there data showing the height of the Demon 750 Carb vs the proform 950.
I understand that both Carbs are Holley replacements, similar sizes?

The carb that I ran was this one:

I would assume that they are very close in over all dimension size, since they are based off of the Holley design...
