Yes, to your '95 motor, they should be the same. Please put your vehicle information in your signature and attach it to your posts so questions can get answered more clearly.

That answer depends on the year of the truck, not the CPI/TBI/fuel injection system.

In '95 GM changed the angle between the heads and intake manifold. Intakesprior to '95 can be swapped on engines prior to '95. Intakes after '95 can be swapped on engines after '95. You cannot swap intakes prior to '95 on engines after '95 and vice versa. That is hte simplified version.

Ok, that's completely off from what I've been told prior to this. And kind of confusing since the CPI ("W" code Vortec) intake is the same from '92 to '95. Or is there a difference to the inside of the lower plenum where the bolts are?

'95 is a confusing year. GM made changes over the life of the engine, however '95 is the most confusing.
