Default Vortec heads and manifold ?

I am considering GM's 350 HO that comes with vortec heads. Does anyone know what intake will fit the heads and still fit under the hood of my 77?

Edelbrock's is to tall to use the factory air cleaner.

Thank you!

You're basically limited to the edelbrock performer vortec intake. You'll also have to use a drop base cleaner. You won't have much clearance - maybe 1/2".

Thanks for the feedback.

By the way, what style air cleaner do you have? My stock style with snorkel over radiator already touches the hood insulation with a shorter performer intake.

Nate 76X suggested a drop base but the factory style already almost touches throtle linkage.

Default 1981 with Votec Heads

I have a 1981 with a Fastburn 383. I used Edelbrock Manifold # 2116 and Performer Carb # 1411. I have the factory air cleaner on the motor but I had to make some modifications to the base wear the air cleaner sits and the hood closes fine. Once your done it does look factory.
