I can tell you from experience from putting engines in my rig.....
without a body lift on a truck with a wide distributor cap:
The Edelbrock performer will fit under the stock hood using a holley four barrel and a short 2" K&N filer and a 360 top... you need the 360 top to get adequate CFM of airflow... under the hood provided you do not use a "wing" nut or decorative top nut and you trim the center and right side (when looking at it with the hood up) of the central hood support bar. if you want the exact part number for the air filter combo... can give them to you.
If you have cast iron cylinder heads the performer will be close to a port match for the stock heads... which means that is the intake you will want to use for optimal performance.
If you are using aluminum heads you might be in a situation where the ports of the stock cast iron manifold or the performer are too small.... the manifold will not cover the ports on the cylinder heads when installed... you will have to use the Performer RPM... which also comes in an airgap configuration.....
If you are in this situation you will need a fiberglass hood, or go cheap and get the fiberglass hood scoop.... and don't cut the hole in the center of the hood... then engine sits to the passenger's of the engine compartment.
