Default Hood/bumper alignment help needed...

I bought my C5 like this, and I'm not sure what the remedy is. The bumper seems to be aligned at the fenders, but the bumper sits approx. 1/4" lower than the front edge of the hood near the center. Do I need to adjust my hood on it's pivot? I noticed the hood is a little difficult to latch closed, too...any ideas how to fix this???

Bump! I don't want to get in there and make things worse - if this is a common issue and someone has a how-to-fix, please LMK!

Lower the height adjusters - bumpers on screws. Check to see if it has an oversize air bridge or anything that could be hitting.

Thank you...did some reading...it's probably the air bridge (there's an indentation in the hood insulation). It's a stock C6 LS7 MAF and intake...and it doesn't seem overly huge. I'm not used to Vettes so this intake design seems really odd to me! How do you squeeze anything in that tiny gap that flows enough air?! Any recommendations? I'd love to convert to front-feed instead of bottom-feed, but that's nothing I can do right now.

Pics under the hood please, so we can all see what is happening.

...here's what I'm working with. It looks like minor marks from contact on the underhood insulation (I just pulled it off to see if it made a difference), but it doesn't look like major fitment issues to me. Is it possible the PO permanently bowed the hood up a little (ie, is the hood frame metal, or is the frame also FG)?

There is another bolt for the hood where the arms are toward the front of the hood, you have to lower the hood a little to see it and get a pic.

You might want to ask the guys with big radiators about this. I do not see the upper radiator mount. When it is installed, it keeps the radiator in place and seals the radiator between the air filter side and the fan assembly. It also had an Elite Engineering piece - did the PO tell you about any performance mods it might have?

Yes, but nothing that would have affected the hood alignment that I can think of except that he used to have a Vararam on it (went through a puddle and hydrolocked the motor with it). Radiator doesn't move at all; I took the top cover off to check the gap as I'm planning on installing an intake with 4" piping instead of the pancaked air bridge...turns out there's appx. 5" between the top of the radiator and the bottom of the hood. I'm going to get a more exact measurement later this week by closing it on to some putty; sort of a giant Plastiguage.

Do you have any shims under the bumper cover where it meets the hood? If not, try using some to help push the bumper closer to the hood
