I'm probably the only person to note this, but I would like to raise a possible safety issue with the hood spacers. When in the fire service, one thing that we observed is that if a hood became detached during a crash, it would go through a windshield and almost always would be fatal due to decapitation. Raising up the back of the hood makes it possible to easily come loose since the firewall is no longer behind it. This is not a modification I would want to do. I do realize it is cheap and works. However i think this is not wise to do.

Duly noted it does make sense and I can see a clear concern for such action besides I like my head where it's at thank you very much. How about getting under the hood in the back with a crowbar and making your own cowled hood a little rough but it might work? But seriously that really is a good point.

Actually I have another idea. Similar to yours, but easier I think. I am going to cut out a large area on the hood and use louvers made out of an aluminum sheet. It is soft and easier to work with. Afterwards you can just buff the marks out.

How about this idea? It would have a catch pan and drain hose hanging under the louvers to manage any rain water intrusion. You could use stainless bolts all the way through. Or mabe there is another way to suspend the catch tray?

A little inspiration from that. I was thinking if you were to cut along side both ridges, you could raise the center panel toward the back. Then fill the the wedge shaped opening by either welding in a sliver of sheet steel or fiber glass it in. You would have to reinforce the back edge and then fill in the opening with a screen. What think ye??

Is this what you mean? Make the Louver a wedge shape? Would it still have the Louver slots Or vent on the back edge only?

What little drawing program you got there? But yes vent out the back. You could do it with or with out the louvers though. It would make a shade tree cowled hood.

Go to here on your computer. Get there by clicking on your start button, then follow what I have on the screen. Double click the "Paint" button to open the program.
Once you have finished your stick drawing and want to save it press:
File Save as (Name the File) and then (select JPEG) in the box below.
That way you save it as a JPEG file in your pictures and you can attach it like I have.

No, it's pretty easy to use. Can you get there following the commands I posted.

Click on:
1. Start Button
2. Click on All Programs
3. Hold your mouse over Accessories another pull down menu will appear
4. Put you mouse on paint and double click to open it up.
5. Select the shape you want to draw by clicking on the menue on the Left.
6. Put your mouse on the screen, click and drag where you want the line to go. At the end of the line click and the line will stay on your drawing pad.
7. Then just repeat step 5 and 6 for more lines.
When you go to save it's important to save it like this (as a JPEG) so it's easy to load on this site. Was the wedge shape what you were thinking of?

Yeah I've used it before and pull it up for the grandkids all the time. Its just that I haven't used it in years and didn't know they had improved it that much. Did I say decades it seems like it.

Cool... Maybe others that didn't know, can get there using my instructions and use it on the site.

Is the wedge I drew what you were thinking about? for your vent?

In my situation having a conversion , it is pretty busy under the hood and a catch pan is out of the question. Everything under there will take the presence of water, so there is really no need of a barrier.



It is a little hard to see, but there is two triangular shaped areas at the front corners of the hood. I will cut these areas out and fabricate louvers out of aluminum for those areas. In the back of the hood over the center I am installing two oil coolers with fans in the hood. The fans will be visible. and since there are two, it will be concentric. I have just finished the plumbing on the engine and have not quite bolted it in yet. Unfortunately I have to take a few days and finish putting the new tranny and clutch in my truck so I won't get to any of it until next week.
