I dont care for the "looks badly added" look, but I like the concept. If it was cleaner and didnt look like an after thought it would be tits

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

I don't know about a 67 lower vallance, but the one in that rendering looks like the lower air dam from a 3rd gen rs. I had a 92 rs 25th anniversary ed. It had nice ground effects all around.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

yeah.. we got off subject from the 69 Camaro valance for a bit... but thats still what Im going to go with.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Well I like the hood and the function it serves. After thought? Huh... I don't know why you think that. That truck was built for one thing and that was to go fast and take curves. The truck can handle it's own against most stock vetts! Going straight are on a road course.
How about this one.
This is Rob's of 'No Limit's' Hellboy and it is one bad truck and it happens to be of our own years also. By the way both of these trucks are members on here and vendors.
I'm sure either one would help you get the hood are the spoilers.:chevy:

I LIKE the functionality of the CF Hood, I dont care for how the snorkels dont have a seamless look is all. It looks to me like the holes was cut and the inserts were just slid into place.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

The function you speak of is? As far as getting air into the engine, it probably doesn't really do that very well, there is a reason why forward facing front edge scoops on hoods are pretty much absent from racing after about 1970 on full bodied cars, they are just not very effective. Looks cool, and looks like it should work well, but they really don't, not by themselves. Modern race and supercar ducting will almost always provide a defined exit path for what ever air is sucked into a duct and that exit path will have some means of producing a low pressure area over it to pull air through the duct.

As far as lightness, the gain from going from steel to fiberglass will drop the weight of the hood by half, carbon fiber will drop the weight maybe 10-20% from fiberglass, so it's diminishing gains from exponential prices, fiberglass is hundreds, carbon is thousands. carbon is sexy and it's high tech, but an aluminum radiator will shed more weight than a carbon hood if you've already gone fiberglass, just sayin'.

Robs Hellboy is really a race truck, lots more going on with that truck than a couple body mods and some suspension tweaks, there is a build thread of it around here somewhere. These truck, done right, can handle really well, despite the pretty terrible aerodynamics, because they are very wide it makes them really stable. A Blazer has the same wheelbase as a C6 'Vette but it's 6 inches wider.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

I only brought it up because you all mentioned the hoods. Yes both the said trucks are proven race trucks. I'm sure they have more in their wheel's than I have in my whole truck.;):lol::lol::lol:

One of my favorite pictures of Hellboy!

Here is another Optima challenge truck it looks a lot like the drawing. This one was the one I was looking for to begin with.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Well IF the holes are piped directly to the intake then they would serve nicely as ram air intakes... if they just are open holes to the engine bay then I see your question.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Now this one I like. Its close to the look Im going for.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Yea, but that was kind of my point, all those "Ram Air" systems from the '60s didn't really work very well.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Ram air does not lend itself well to any carbureted application really. Unfortunately when you ram air into a caburetor venturi with such force, the pressure in the venturi actually increases instead of dropping like it is supposed too. There becomes too much air and it cant get out of the way fast enough and forces itself into any opening it can find including the jets and the float bowl. Honda and Kawasaki figured out that they could overcome this by piping a line from the ram air tube to the float bowls on their motorcycles, thus increasing the pressure in the bowls as the air pressure in the ram increased. Allowing the venturi effect to work properly. Cowl induction on the other hand takes advantage of a semi stable pocker of air at the base of the windshield. While all the air is turbulent flowing under and over the hood, the pressure of the pocket of air at the base of the window was more like the air would be if the car weren't moving which makes for better conditions for the venturi effect of the carb......

wow that was a ramble sorry.... I just love performance technology....:uhmk:

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Ram Air has all kinds of issues, the ill effects of pressurizing carburetors is just one of them. In most of the '60 applications of forward facing hood scoops air pressure and density were all over the place as humidity, altitude, attitude, and temperature changed, basically guaranteeing an inconsistent air fuel mixture. Same holds true, to a lesser degree, of electronic fuel injection, most of the OEM PCUs are not really fast enough to adapt to wildly changing intake air quality which is what a crude velocity based attempt at free forced induction gives you. Best thing you are going to be able to do for consistency is to give an engine a cool air source without turbulence at predictable pressures. To try and force some inconsistent air source into a engine based on aerodynamic guesses will lead to combustion that is constantly varying between rich (dirty) and lean (destructive).

...and yes that is why cowl induction type scoops or rearward facing scoops basically replaced all other types.

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

with all that being said... then how in the world does a carbureted turbo vehicle even work? Would a blow through set up not be the same principle as what you're saying dont work? or even draw through for that matter?

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Exactly... carbureted turbo setups don't work well.... not nearly as well as efi. A blow through carbureted turbo (where the turbo is before the carb) are really hard to get right. You need a high cfm carb, the jetting needs to be perfect, and you need high fuel pressure and float bowl air pressure.

A suck through (where the carb is before the turbo) is much easier to manage. Because the air is being pulled through the carb by demand rather than being forced into it. When the throttle body closes the pull stops. This is why superchargers are so effective, and usually have the carb(s) on top.

both have disadvantages. Push through are really hard to get right and maintain tune, while the pull through turbos run the risk of ignition in the turbo.

superchargers dont run the risk of ignition because they dont use hot exhaust to spin the turbo, they are belt driven....but they rob initial hp.

like my performance/dyno teacher used to say "theres no free lunch"

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

A lot of blow through boosted setups in the carbureted days used pressure boxes, where the whole carb was incased in a box so that the carb was operating under a higher relative pressure. By doing it this way pressure differentials from the floats to seals, etc., are the same as they would be at normal atmospheric pressure with a raised relative baseline. It's how all the Paxton superchargers in Shelbys and Avantis were set up. I don't think any of the factory carbureted turbo setups (Saab, Buick, Trans Am, Corvair, Porsche) were blow through, I think they were all draw through which is simpler to setup and get to run, but has the disadvantage of lag and surge which all those early setups had in spades. Stomp on the pedal..one Mississippi, two Mississippi, holy crap!

The wait is over, lol

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

I saw it on F/B and it is awesome man, nice work. Now when are we going to see the real deal, that is the question!:chevy:

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Looked at this three different time before i noticed the C/28 emblems lol Thats awesome!

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

This thread keeps on coming up so I thought you guys would like seeing this truck from super nationals. Not a valance but it does have camaro ties

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

that Some Bish took my idea! lol
Damn thats BEAUTIFUL! And Exactly what Im going for!
Thanks for sharing that

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

That is awesome looking right there ! Has anyone accomplished this yet or even attempted it ?
I think I got a woody looking at that :D

Peace

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Here the thread the black pic came from.... I actually thought it was a real truck. Member Hellaflush3d did these. Nice renderings!

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Thats an awesome rendering bud... I wounder if you could do one with a SS grill with the hide away headlights for me?

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

Love the C/28 emblem

Re: 69 Camaro front valance and spoiler on a 67 c10?
 

I like that touch to.

I also would like a c z 10 emblem for it!:chevy:
