The Dodge Challenger Message Board

Hello, here is my weekend bracket car. Not a challenger but its a dodge

I love 70 Coronets.

Vert nice

Looks Brutal&Violent! I love it!

One word : Beauty

One question, 440 for power, why the dual hood pins? Is it for reinforcement? I dont know much about drag racing, or any racing for that matter,LOL

The other two keeps the engine attached to the hood!

Btw; The dual scoops matches the grille very well.

Wow, always loved these bodies. Really really good looking.

Is it a real superbee?

Looks like there are pins at the back of the hood too Eddie. It must be a 'glass lift-off hood. Good quality finish if it is.

Isn´t it a relief to see a car with "old style" high wall tyres?

It get's the car higher from the ground that way anyhow? Them oilspans really are low and very close to the bumps... you know what i mean.. And all of them 6 hood pins probably are needed for more reinforcement with that complexed bends in the front end of the hood.. Or else it would be hanging with no nice shape at all, because of the heat, making the fiberglass less stable(?)

What engine is it in this machine, 440?
Are the headlights painted "dummies", or some kind of aftermarket..?

I dig this car!

Looks like slicks on the rear and "front runners" on the front. The car will be trailered to the track I guess?

Yes, maybe you are right. I believe that air pressure is the most important factor though. At high speeds, the area between the grille and the radiator should be a high pressure area. Maybe the two extra bolts are ment to keep the hood close to the radiator support, so that there will be no air flow leak (so that all of the air is flowing through the radiator and no-where else)?

With fiberglass hoods you have to have some way of holding them down at the front edge because with just two pins they bend up alarmingly in the middle when at speed on the track.

Thanks guys, When I put the fiberglass hood on I just used 4 pins for the lift off hood. But on top end the front of the hood would bend back and actually broke the bracing underneath. So I added two more pins up front. When I get another hood I'll just do 4. Right now its just a stock 440 with eddy rpm heads and a 613 cam. Best pass of 10.59 at 128mph. I'm working on a 470 to try and drop it to 10.0 next year. Oh yeah its a real 70 bee. Thanks again

Oh, OK thanks for the answers Dave&440, I had no idea those fiberglass hoods were that fragile at speed. For a mild build, that 70 Bee would 'sting' you pretty good!

Depends on the hood, but the 'race weight' versions are too thin.
Check out this pic I took at the top end in Santa Pod, 2 years ago :

Yep. My mate Andy Robinson was having this trouble with his '67 Coronet. I think it is worse if you have a hood scoop as it forces air to the underside of the hood more.

It looks like he had a pin in the middle of the front end of the hood also...(?) And still it lifts the hood like that? It must be a really really thin hood like you said fbernard... Normally the fiberglass hoods are way to solid to lift up like that... Nasty!

Hood at speed!

The fiberglass hood on my chally is reinforced, not race weight, and with just 2 pins and the hinges holding it, it bows up and down quite a bit in the middle, this is with a scoop.

At 120 mph, it was starting to look pretty scary, over 2 inches of flexing, so I havent gotten it up that high since.

I cant imagine race weight. I would pin it everywhere!

Which type of hinge springs do you use?

Mine is the same as the Challenger in the pic, but I have 2 pins on the front, in the middle (that's a total of 4 on the front, 2 in the back).
I didn't try it on a quarter mile (yet), but I took 220 km/h on the Nogaro racetrack (wasn't looking at the hood back then, what was I thinking??) and the hood is still there. The two extra pins really helped at speed (before, the hood would twist and bow right after 110km/h).

The springs are lighter springs that really just help me lift the hood a bit, I have to prop it with a bar to keep it up. The drivers hinge is very hard to move, too, even after greasing, so it keeps the hood down. The hood flexes in the center, all around the scoop, not at the rear.

I will definitely secure it with more pins if I want to run it at speed again.

Do you have a race weight hood? How much did it move at 110 km/h? I would figure 4 pins would be enough for that....if its reinforced.

Mine is not reinforced for hinges, it is simple pinned on. I have to remove it every time.
Before, when I had just the 4 corner pins, it would flex in the sides real bad (I swear you could slip a hand under the hood from the side). Looked like the engine was pushing up at the hood. And it always moved.

Friends driving in front of me told me it was scarier from the front, with the lip of the hood raised like a shark mouth (just like the pic).

I ordred more hood pins, and simply added 2 small pins at the center of the grille (I added brackets to places that already had bolt holes). I tried it like that, and no more problems, so I didn't add any more (I was planning to add more on the sides as well).
