If I remember correctly (at work now) it had the intake, don´t know if it is the original or not. Best way to look it up?

Here's a link to the casting numbers for the intake manfolds. The original intake will be a cast iron spread bore intake. Many people think that the 71 340 intake is the best stock spread bore intake the factory put on them.
