Approx cost of glass flat hood and hinges (67)

Put this in tech as the topic is really about heat management
Low cost and interesting to me

Debating doing something subtle but effective to reduce underhood temps, incorporate a cold air setup but extract as much underhood heat as possible.

Not much experience with glass but seems simple from the little Ive done.


Some newer vettes have an interesting extractor behind the radiator, some guys space up the rear...any bright idears?
Love the sttel cowl one I have but get bored. Plus its heavy as hell.

Would you recommend using pins in addition to the latch, is it really needed?

For a 67 El Camino, why not install a cowl induction hood (2" rise) ?

That would give the hot air a way to escape. And cowl hoods for 67's are cheap !

Re: Approx cost of glass flat hood and hinges (67)

have a cowl induction now...when I removed my ac I took the opening for the suitcase welded a lip on it in case a yunick type box was done.

This would need fab work which Im not capable of doing. Once ran a camaro air cleaner (cowl induction) but that was with the old motor that looked more stockish

Re: Approx cost of glass flat hood and hinges (67)

The ZR1 corvette uses a neat hood that extracts hot air from the radiator...if the compartment builds pressure with hot air to boot..if that was removed, get cold air to the engine and looked good to boot..kind of a challenge without spending a ton .

MB uses a neat firewall that isolated the engine from electronics, brakes etc. Wouldnt be hard to do

If not already done you could ceramic coat your headers or manifolds. Takes a ton of heat out of the engine compartment.

Tighten it till it strips and back it off a quarter turn.

Re: Approx cost of glass flat hood and hinges (67)

The engine compartment and the hood design stock was to draw air in through the radiator and force it back and down against the firewall. Giving it a way to escape somewhere else may create more heat in the long run.

Your just jealous because you can't hear the voices!

Re: Approx cost of glass flat hood and hinges (67)

I have a fiberglass hood and fenders from Glasstek on my 67. It's a considerable weight savings. But the fenders required inner braces to make them match and hold the contour of the door body lines, so some fabrication is required

Re: Approx cost of glass flat hood and hinges (67)

Other considerations...Something like aluminum heat shields over headers to reflect heat down, coated headers-inside and out, take a look at the "turkey roaster" air boxes on the the big block cobras with the idea of ducting your cowl induction hood into it for cooler intake temps (kind of a "take-off" on Smokey's plenum air cleaner), possibly adding sheet metal cover between the top front of the grill to top of radiator (like the ones they sell with a bowtie emblem, etc.) to direct more air thru the radiator, lower temp thermostat, if not already done, fans, water pump pulley changes. All sorts of options possible with a little research..some good ideas have been previously presented here..take a look /search.

Post a picture of your ride and engine compartment, may help spur some ideas.

Rick,

Is your hood hinged or pin on? 99% of the time Iím at the track by myself and hood removal and install (Ď71) would be a PITA and risk scratching stuff up on a windy day. Been looking at making braces/brackets for glass fenders to support hood hinges. Could end up with the weight cancelling out though.

Re: Approx cost of glass flat hood and hinges (67)

Cant get pics to post on here unfortunately
I do have coated headers....sure would be nice to figure something out to keep a few plug boots cooler. THey dont touch but still singe 1-2 here and there.
Running the inner fenders and rubber seals. Have considered either ditching those and fabbing up something light/that looks clean and give more room or glass.


Keep the idears coming....lighter I can get this the better. Not up for adding power but removing weight is just as good. If im creative doesnt have to cost that much. Came close but decided to get my 1500 back on the road


Hinges would be whatever came with the glass hood?

Pin on, but I bonded and fiberglassed inserts to the bottom side so I could bolt it to a set of lighten stock hinges. I got sick of constantly removing the hood. It has worked well for close to 2 years now.

Re: Approx cost of glass flat hood and hinges (67)

Rick, how much weight did you save with the switch to fiberglass fenders and hood compared to the OEM parts?

I really don't know. I never weighed anything, but i'd say 20 lbs per fender if a 67 fender is 25 lbs the glass fender is 5lbs.

I haven't had a steel hood on the car since 1998, so it's hard to guess that one. Probably at least 20lbs lighter.
