Is there any way to reshape this hood or will i have to build something that will hold it in the correct position from underneath. I plan on using some of the dz fasteners around the edge to hold that in place but the actual scoop will still be lower than it should. Thanks

I made a glass hood but got fed up with it moving so I used the same mold and made a carbon fiber hood... that stuff is great

I turned the hood upside side, put a little weight on it after a week or so, I put some reinforcing sheets of fiberglass across it. Works great now. The edges if you just lay something heavy on them, they will go back down to where you them, or close anyway. At least worth a try.

A properly made fiberglas product will retain its shape even in hot sun (Corvettes !!!). This was likely made with no lips on the edges or any support to speak of so it was just like a piece of paper - free to flex as it pleased. Even being taken out of the mold too soon would have an adverse affect. There are still cheapo hoods and other products being made and sold today as "lightweight". However, a quality manufactured product can still be light and structurally stable.

Heat from underside as even as you can an area no more than a square foot or so at a time. When it starts smoking, weight/ hold untill cool enough to touch. After you get it where you want it then add a bow or brace. I use thin-wall tubing or 5/16th rod. I`ve straighten some really nasty/cheap glass parts like this. Still looks good 20yrs later Last edited by 6bblFLASH; 01/10/13 08:11 PM. 70` Cuda`,440 6BBL Jerico,Dana 4.56 Still on 93 Pump Gas 9.87 @ 136/1.31-60ft.`09 Mopar Nationals PASSON PERFORMANCE "Stick-Shift" Champ! 2013 StickShift Challenge Winner@ Mopar Nationals!

I usually split it length ways and glass that to the hood once you get it back into shape... usually 3/4" or 1" fiberglass tubing(sold at any fiberglass suppliers).... just because its a light weight hood doesnt make it junk

If shape is still not correct you can either force down with weights or even use a long self tapping screws. Then apply heat to the hood with a hot air gun, just get the hood warm, you don't need to get so hot that it removes or burns the paint. You will have more success with a newer glassed hood than an old one, as glass is still malleable for a while. After heating, leave hood in place for a couple of days to settle. Assuming hood is maintaining the shape you want, you can glass in some supports. Carbon fibre (CF) hoods are great, just ensure the mould which the CF hood is to be taken from, fits your car perfectly, as CF does not move, has zero flexibility, unless it paper thin. . .

Would this work or could too much air be a problem? Think of it this way.... you can never force enough air down that carb.. a forward scoop in the right location acts as a really small super charger but without the belt(its pressure)... but the carb needs to be sealed to the scoop... plus with the scoop sealed off it doesnt allow the hot air from the engine bay into the carb

I think I will try and construct something rigid to catch air and hold up the center of the hood all at the same time. Its a 6 pack scoop so it has a pretty wide opening but I will think of something I'm also gonna flip the hood up side down and put some weight in the middle on 2 sawhorses I believe that will help. The biggest trick will be constructing something to hold the hood up that isn't gonna be too heavy...
