The reason for doing this concept is my wanting an up/over air bridge for dual air cleaners up front, I have most of the hardware for that, but the pesky hood is in the way, and fabbing up hinges that BB69 drew up for me is beyond my time/effort/capability curve....so I got some hinges off junkyard Sat AM wandering around in my sandals full of Florida junkyard sand on a sunny day....
I going to fire up the saw to fab some wood blocks and clamp crap up in some sorta position to see if my theory works out.....

IF it does...well, I will have to see how to do a few things.....

#1 is to lighten the hood, going to take a saw to that huge flat panel area under the BB add on scoop, that may well save about 20 lbs of glass....that damn hood is HEAVY.....then I will see about some aluminum braces for the hinges...dunno where I will find support for them as anything up top there is all glass, no metal I find anywhere....me suspects troubles there....maybe I can poprivit in a 1/4x1" maybe 2' long piece of aluminum up and under the fender/hood edge.....hummm.....

so far the hinges are off a Ford Taurus, and a OLds Silouette/Lumina Van...

small and light, and seemingly having the function I want in either pair, I cut the springs off the Lumina hinges, as they are in the way...:smack

What do you mean reverse? Do you want the hood to open from the front like a normal car or is there something about the C-3 hinges that are in your way? Sorry for the dumb questions but I'm a C-4 guy, just trying to help.:D

Gene, Who is BB69? Post some pictures of the Taurus/Lumina hinges. Did you see the pictures I posted of the Magnum hinge? I think that might work for a reverse hinge but, what do you attach the lower hinge too?

Well you know, the hood hinged in front, like a C4 bonnett, and so if the paint wasn't so nice 12 years ago when I got this car, I would have cut the fenders, and done a complete C4 style bonnet, similar to TT, but that's destroying the paint job....not ready to repaint just yet....

so what happens on a C3 is the hood lies down on the leading edge, right up against the rad/a-c condensor.....no clearance for my up and over air bridge, similar to C4 up.....see site for a engine pix....I"m tired/bored with the box over the KN filter and hood/cowel induction....that pix was allmost as tired as me, but thing are somewhat cleaned up now...not quite so worn looking....

so the hood needs be reverse hinged, hinges like a 'normal' car, in the rear....meaning they need be very compound to raise the rear edge outta the way....

I was thinking of doing that for the front, but it's too much, as BB69 showed me....

I"m sorry man, I had you confused with another guy off CF, we discussing/he has helped with CAD/CAM drawings for front compount hinges but they are too complicated for me to build....am still messing with the hinges.....my dig it all camera don't like this computer, so I can't easy post pix just yet, another time.....

the hinges are compound with two bars oddly spaced to each 1/2 of the hinge mounting plates.....METHINKS I can sneak the Lumina hinges in there sans springs.....really don't want counterbalance there anyway, too much stress loading on what I will assume is allready weak enuff spots....

OK I follow ya now. How about something off of the late 80's Buicks and Olds They are a dime a dozen in the junkards and the hinge system lifts the front of the hood first then slides the whole deal forward and up so the hood would be above the front bumper area. You would probably have to lengthen the hinges so that they will clear the nose of the car.

Gene, You don't have me confused with anybody, I'm the complicated hinge guy from the CF. You just have my name wrong:D

[/url][/IMG][ Here's what I did. I took an air cleaner assy from an 85 and mounted it upside down under the radiator. I then made a scoop to collect the air.

Gene: Just a thought...and you'll probably hate the idea for your use...but have you thought about just using hood pins to secure the hood and having a hood that lifts off completely? Sure would make it a lot easier to work on the engine that way.

That is an outstanding design! :thumbsup:

Can/did you test to see if it has a ram air effect?

Also, did it effect the air flow through the radiator?

Pretty cool! :thumbsup:

I haven't had a chance to test it yet. I hope to have the car running by early June. I'm hoping that with the aluminun rad and high flow electric water pump I won't have a cooling problem! As you can see there are also dual 11" spal fans that are thermostatically controlled. As far as the ram-air effect, I sort of copied a system by a company in Houston called Ramair Specialists. They make a similar system for pickups and Chevy Impala etc. I even bought one of theirs but it was too big to fit between the sway bar and the frame crossmember. Another $250.00 wasted. :cheers: Art

Yeh, I have thought of that also...but that makes it a temp storage problem just to look at oil/water....PIA to deal with....dunno what do do there....

going to cut out the hood center of all that glass, up under the BB bulge aded on and see if that lightens it enough to make that an option....

as long time ago, I can take 3/8-1/2 inch Stainless bolts, cut them off, taper the ends in a drill press to bullett shape, and secure with stainless fender washers....all out of say West Marine.....maybe 25 bux worth....

BUT, that depends on my cutting that hood out, and seeing what, if any help that is in significantly lightening the hood up......I ain't 25 anymore....

There is hood latches available that will tilt up like the stock hood but can also be removed in a matter of seconds. Mid America might have them

I'll see if I can find them.

M82, I appreciate the time looking it up, but they are detachable hinges...and do not seem to raise the hood up and forward from the look of them in the pix.....the installed pix with hood up does look encouraging I admit, but when looking at the shots of the hinges alone....I can't see any compound action there....

maybe this week I brave enough to cut the hood out, and see about weight factors and 4 pins, and have it over with....

I still think of say a road trip thing, to check oil or summfin....that is then a PIA to deal with....and so the reverse hinge thing again....can't win....

Gene: A quick OT question. I ripped out the wiper stuiff from my Vette. I plan on using the cowl induction L-88 hood that replaces the wiper door area. Do you know if that hood is any heavier than a stock big block hood?
