Under Hood Clearance

[john108]

I know that this topic has been discussed many times but I haven't seen a definitive answer with the same hardware (I may have missed it!).  I have seen various combinations of hardware and body styles.  I have even beat around the bush with this question before but approaching a deadline now.

My engine is getting close to going on the Dyno.  I would like it tested with the same configuration as when it is installed in the car.

My major concern now is whether to install a 1 inch thick phenolic spacer below the carb or reduce it to a 1/2 inch thick spacer.
When I did the math, it was very close, but I can't find it now.

The configuration is for a 1968 Dodge Charger (NO Hood Scoop or Bulge).
440 block
Holley Street Dominator Inlet Manifold
Phenolic Spacer with gaskets
Proform 950 Carb 67202
Air Cleaner Assy-Drop 1.25 (K&N 66-3040)

I hope someone has some hands-on experience and can put my fears to rest.
Thank you,
John

John very close even with the 1/2 inch spacer, but the spacer is a must for the heat insulation,
I got a bit more clearance changing carby kick down to cables, slight dimpling and trimmed the lip ring that sits on carby, don't leave too much air cleaner stud up ,

Put some balls of modeling clay around the rim of the air cleaner and close the hood...measure the clay.

Thank you both.

I was planning on having the correct thickness spacer on the engine during dyno testing.
