Retaining the cross member? Symmetric fuel rails?
BTW, are you getting an engine cover? I wonder about dremeling a small section to allow easier access to the oil cap. Also, are you guys able to retain the stock oil cap? Just seeing if you are going down this path.
Also, with so much invested, have you considered an engine window of some sort like the ZR-1? A properly vented and windowed painted OEM hood (i.e., keep things clean and not too aggressive looking) would be nice.
If possible, please feed some photos of the fitted components.
