Default 4 inch cowl hood ?'s

I couldn't figure out how to add a picture of what I have? It asks for the url location for the pic, but, its on my desktop? Anyway...its a 454 (496 lunati stroker), victor dominator intake with a 1450 adapter...running an ATM 1050 e85 carb (highly recommend ATM). I have a 16" and a 14" Xstream air cleaner. I would run the 16" if I could, but, I don't think it would clear the front part of the cowl...in fact I think the 14" will be close as is. What I need is to find someone running something similar height setup to see if a 4 inch cowl hood will clear? I don't want to buy a 4 inch cowl only to find out it won't clear. About the only way I could think of figuring this out would be to measure from the base of the intake manifold up the front rim of the air cleaner. Mine is 11.5 inches. The its right at 12 inches to the top of the air cleaner. If someone running a 4 inch cowl hood could check theirs for clearance...that would be extremely helpful! Thanks...

several ways to add pics,
you want to add an attachment if there on your PC,
hit the Go Advanced button under the Reply box, then attachment, it looks like a paper clip..
find the fie with browse, then upload..
.
real easy to add/delete pics in the Garage too, go to your User Control Panel, then Garage..
.
on the hood,
get a straight edge and lay it from the header panel to the cowl, and or fender to fender,
1 on each side of the carb..
that will give you some idea ..
plus the hood probly has a little rise in the middle..

Thanks for the tips...however...there is no paper clip or any way to add a pic. I think its because I am new or something. There is a box in the lower left corner that says I can't attach pictures...which I didn't notice at first.

Anyway...I put a straight edge across the hood and the top front of the air cleaner sits at 3 3/4 inches and the nut on top sits at 4.5 inches. I could probably lower that maybe 1/2. Hopefully someone with a 4 inch cowl can give some idea of just how much room there is. Thanks.

Does your 14 inch fit today?
A short 2" air cleaner or something fit that is close?

If so, set it up.
Then buy some child's clay from the dollar store.
Make a chim ney shape out of the clay.
Place it at the highest point of the cleaner that fits easily.
Slowly close the hood.
Measure the distance of the smashed clay.

Don't forget to include clearance for your threaded rod and wingnut on top of the air cleaner.

I don't have a hood except for the stock one. I would need someone that has a 4 inch hood feed me some info to see if I can figure out if a 4 inch is high enough to clear my setup.

I think that being below for a test and measuring with clay is best.
You might consider a piece of 16 inch round cardboard and multiple stacks of clay on top of a short air cleaner or base the fits.
Each situation is different.
The underside of the hoods can differ in design.

Dale is adjusting a 1250 CFM on Robert's 535 ci BBC with high rise, and carb spacer.
On the trailer, you can see that they cut the hood. Originally, this was for a stack style air cleaner. Well with a screen on top.

They cut the hood circle larger, because they use a regular air cleaner on for transport to keep rain and stuff out of carb and engine.

I don't know if a drop base air cleaner bottom would clear that 1250 CFM carb setup.

You might also find that the carb is not centered on the center of the hood. I forget, yet I seem to remember they are shifted to one side.

Then I will be quiet. The truck in the image is a 5th Gen and not a '67.
Without knowing the shape of the underside of the hood, it will be difficult.

Ya...I am hoping someone gets on here with a 454 with a 4 inch cowl in a 1967...ha...might be waiting awhile! A 66 to 69 might be close enough as well? I just dont want to lay down $600 for a 4 inch cowl only to find out its not tall enough. Based on my measurements...it would be close.
