[601HP]

Michael,

You'll discover it fits, or not, when you put the engine in the car. I have a Hi-Tech fiberglass car with a 427 side-oiler, medium rise heads. Here are my experiences.

My first intake was a Sidewinder with a Holley 750 and a Turkey pan. I had to lay a 2" x 4" piece of wood on the top of the Turkey pan and whack it with a hammer to slightly bend it's base area to get it low enough for the hood to close.

Several years later I removed the Sidewinder and changed to a Tunnel Wedge with 2 Holley 600's and a pair of S&H air filters. I had to do some grinding/contouring to the hood's oval port to get the hood to close around the S&H filters.

Regarding Ernie's comparison of ERA to Hi-Tech; a friend several miles away has an ERA with a 427. The car is about four years old and the unit number is somewhere in the middle 500's . His car has a little more vertical hood clearance than mine. Maybe 1/4 - 3/8"

Good luck.

David
