Removing the plenum?
Hello,
I have a 1990 L98, stock, and am trying to remove the plenum but for the life of me I can't get it off. I removed the top 8 runner bolts, the 4 bolts on the TB, and the cable bracket. Are there any bolts that are hidden/I am missing?? Or is it just the runner gaskets keeping it stuck in place?
Thanks for any help!

The upper runner gaskets are likely making it very tight; try smacking it with a rubber mallet. Mine is now so "loose" that I can slimply smack it with the heel of my hand and it is free.
Also, remove the vacuum lines or the right rear and the brake booster line on the left rear. Finally there is the MAT sensor connection under the center rear of the plenum.
When installing it, be sure to finger start well all the plenum bolts before wrenching on any of them.

The manual actually suggests gently prying it up with a screwdriver. I just put the engine hoist on it. Very lightly it popped right off!
