Default Edelbrock D port accessory bolt hole layout needed

Hey guys. Im working on a type2 power steering pump solution for my 67 GTO. I have edelbrock D ports but they're in the car so it's kind of hard to get a really accurate measurement on bolt hole spacing. Does anyone have a file with the holes laid out by chance? I'm using a later 11 bolt waterpump if that matters.

-Nick

I have mine off of the engine. What do you need exactly?

This is my mock up template. I need exact center to center x/y axis distances between the 3 holes I'm using for standoffs.

My round port E heads have an identical bolt pattern to a late 6X head if you have one around.

I'm thinking I read that the bolt dimensions are the same as on a SBC. Thinking you can use the set-up already being used on the funny looking little orange engines.

Second thought... I think it was the vacuum pump mount for a SBC...not power steering.

Interesting read and Ideas...

I can give you that info Tom V.

Nick here is the bolt hole numbering for conversation:

Hear is a picture of the bolt holes on the Drivers Side cylinder head for some stock Pontiac heads and also Edelbrock E-Heads.

The holes would be numbered:

Bolt hole (Top left of head) = #1

Bolt Hole (Top left of Head Core Plug) = #2

Bolt Hole (Bottom left of Head Core Plug) = #3

Bolt Hole (Bottom Right of Head Core Plug) = #4

Bolt Hole (Bottom left of Head close to head gasket) = #5

Bolt Hole (Bottom right of Head close to head gasket and exhaust gasket ) = #6

Tom V.

Call me Nick and I will give you the locations for the holes you need.

Ok, based on that Tom, here's the holes I'm using to mount. I need measurements center to center on

-2 to 6
-6 to 5
