Default Lightening Hood

Any tips on how to lighten the hood i.e.-remove the supports. It look like the supports are glued to the underside of the hood and can be removed with some persuasion. Has anyone done this out there?

Thanks,
Ted

I've thought about it...

What I've come up with is that you could cut all of the support bracing thats currently on it out, and glass in a set of ribs in an X shape to give it some structural rigidity.

Not a clue as to how much it might take off the end weight...

The other would be to either lay a thinner hood, or to grind down the current hood, but that would make it fragile to handle! :yesnod:

I have a frameless hood. It's held on with 4 hood pins. It is SO much lighter than it was before I removed it ( ok ok it self destructed and I am too cheap to buy a new one.)

The pins actually screw right into the where the latch pins go up by the windshield and you need to weld up a Z shaped bracket for the pins down by the headlight. piece O cake if you can weld and drill a hole. :smash:

I haven't checked out why, but the aftermarket is 1/2 the weight off the stock hood I took off. Believe me I moved them around enough in the last 2 weeks I can lift the aftermarket hood off by myself but need help with the stock hood.

Can you give me the measurement from the front center of your 88 hood up to the first point right where it drops into that groove .I want to put that hood on my car but not sure what it will look like with the hole I will have to cut out of it.

That is exactly where my hole starts. Do you think that hood would work? http://temp.corvetteforum.net/c3/hotrod12

And how much lighter is it in pounds? :smash:

I have hinted to the wifey about 3 times in the last month that I want one of those L88 hoods. Weight savings is motivator. :jester

big

it looks close but I can't be sure you would be best to measure where the opening in the hood you have now to be sure

74 vert

I just weighed the hoods with an old bathroom scale,
stock hood from my 74 40-42 lbs
L88 hood 24-25 lbs

Well it all started one day when the hood release cable broke and I was trying to open it. The car was leaking antifreeze ( turns out is wasn't even my car but the previous car! ). The frame just seperated!

It only seperated a little, enough to reach in and open the hood. But when I got home I finished the job. It just pulled right off...

BTW I can pick up my hood with one hand...

427V8, How did you remove the frame?

How hard would it be to make an accurate and stiff part from aluminum?

lighter hood? These things don't weigh very much to start with! I didn't put mine on a scale, but when I had it off to replace the A/C condensor hose, I couldn't believe how light it was. The hoods I used to move around at the Volvo, Mazda,Jag, and Range Rover dealerships were much heavier. Even the aluminum ones on the 960's. How much weight can you save and at what price?

Should be pretty cheap if you modify the stock one...

What we really need to do is figure out how much our fiberglass weighs per square foot... and start pulling square feet out :jester
