Will this fit?
 

I have a 1974 Z28 with a SBC 350 engine that has a factory 4 barrell intake with a carb spacer on it and a Holley 600 carb,I would like to swap the factory intake for a Edelbrock Air Gap and a Holley HP 600 carb but the Holley HP carb has no place for the power brakes to be hooked up, can I use a 1 inch carb spacer with the tube for the brakes on the Air Gap intake with the Holley HP carb and will it all fit under the stock hood of my 1974 Z28?THANKS

Are you sure the manifold doesn't have hole to use for your brakes? I don't think I've ever seen an Edelbrock that did not have one. I know the Air Gap I used on my 383 had one on the rear just below the carb. mount surface?

The intake has the hole there but my Holley does not have the tube coming out the back of it for the brakes or pcv so if I place the carb on the intake its right on the hole no room for a fitting.Thanks
