Upgrade intake manifold?

Drivers seat?? you are supposed to be looking at the driver's side of the engine block. Anyone that changes oil for you can let you know what it says.... OR..... look under the drivers head at the front of the engine block. Flashlight and a wire brush may bring the stamp to light :)

No, what I was saying is I'm too big to lay on the floor and change the steering column out, I'd have to take out the seat to fit. The mechanic that did the steering column did the ID and said it was a 340, I never followed up, but when I looked at the front stamping it said 360, thus the 2 different identifications. I'm under the hood today to put the manifold back on so I'll get a definite ID before hand obviously. I'll upload the pictures of the stampings.
