Dale,
My project is a 77 280Z. The 79 is done lol. I am also want to make it to go over the radiator top support. Yes I understand that the top radiator support doesn't do much support there. I will add a triangle strut brace as soon as I put on the Cobra front clip so I can remove the top radiator support without worry. I see that the stock C5 had the radiator mount slanted and that's how the intake duct can go over it. I will give it some more thought.
LS1Z,
Thanks for the pix. I have it saved on my computer awhile back for reference. You are correct that the stock C5 duct looks a little restrictive. However it does looks alot better than the JTR rubber duct IMO. Plus everything is just plug in.
I will give it some more thought when I receive the aluminum radiator from Summit. I might have to end up cutting out the whole front top radiator support and build another support depends on how I want the radiator to lay or sit.
Thanks for the replies guys. If you have any more ideas please keep them coming.
