93 LT1 intake the same as 94 LT1 intake manifold?

Sorry folks for the delay, As username implies......


Here are some front and Back Picks of the 93 intake. Please note the home made heat sheild on the tube.

Good photos... the back looks pretty much the same to me. The front too, except for the hole for the EGR connecttion. Appears the main difference is the fuel rail cross-over pipe.

Thanks.

So Where is the hole in the front for the PCV hose under the TB?

My post above should have said "....The front too, except for the hole for the PCV connection."

My confusion comes from the Chilton's F-Body manuals.... one version (82-94) shows that the 93 and 94 LT1's have the connection at the front of the intake, under the TB. I know that's not completely correct, because my 94 has the hole under the TB, but it is plugged. Then in a newer version of the Chilton's manual (93-98) it shows all the 93's based on a TBI setup, and that setup wasn't even used after 1992. But it shows the 94's with the correct routing back into the side of the manifold.

Sorry for any confusion I may have caused.

No confusion on my part. Still working on where to run my vac lines for the new 05+ opti though.

Down to either put a "T" on the EGR line or on the Looped PCV valve. Any thoughts?

Thanks for the pics man. I never knew the EGR tube was hooked up to the A.I.R. line. Kinda interesting.
