Wow -

thx for the info.

Technically it was conceived from the humble beginnings of the Quad4 4 Cylinder engine from the early to mid 80's.

You better not let Bbob see that.

The Northstar has absolutely nothing to do with the Quad4.

Theres also a 4.0L Version that was used in the Aurora until its demise :shhh:

Ive read several Quad4 commentaries that seem to point to it as a direct point in the evolution toward what eventually became the Northstar, despite the fact the blocks are different etc. etc.

I own both engines.. Quad4 in my 89 Grand AM SE 5spd and Northstar in my 99STS. That little 4 is great to drive still!
