how would this work on a 5.3 with a t76 on 15ish lbs of boost compared to a stock truck manifold?

I guess their website isn't updated. They don't have the efi bottom (runner portion) on there yet. Only carbed. The efi 102 and 92mm TB tops are on there though. (summit)

i meant the cathedral version. they have the l92/ls3. Going to go look again though.

Edit: Boom! Found it. HLY-300-123 None in stock and says tentative ship date is June 8th. Does it come with fuel rails? It's pictured with them.

They sent out a press release to the dealer network a week ago for the cathedral port hi-ram, so it's going to be available pretty soon. They were boxing them up I believe too.

Why not run the edelbrock Pro-Flo XT?

It fits under my stock Z28 hood!

I like modular design and looks of the Holley better. Simple. I ordered one yesterday too. Also said expected ship date is the June 9th.

And because they don't make L92/LS3 versions. If not, I'd already have one, since they fit easier than the Hi-Ram.

Defininetly a work of art of an intake manifold. I would like to switch out the pro-flo for one when they get a cathedral port version, but not sure it would be a dramatic difference, so I'll probably stay where I am.

I called tech support at holley, talked with Derrick, and he rest assured me, that the new LS EFI intake, will not fit under the stock 4th gen hood even if it is a ws6. said it was 12 inches plus tall. maybe more once the lid is put on it. id still like to see someone try.

It's 12" tall at it's highest point with the lid on it. It can be done.

id be worried about that cracking the windshield.. we all know how fragile those things are. He was saying he will probably space down the k-member a bit too. even a 1/4" will mess up the driveline angle doing that :-/
