L86 vs lt1 throttle body??

[Gron86]

Anybody know if the throttle bodies from both engines are the same? I’m looking for a throttle body spacer for my Yukon Denali, however every dealer is sold out of the l86 spacer. Will a spacer for a lT1 fit the l86? They look identical and all mounting points look the same. But I cannot confirm. 
thanks.

Why did you post this thread twice

 

You don't need a throttle body spacer you are wasting your money.

My apologies. Didn’t realize I posted twice. I simply need to know if they are interchangeable. I have used airaid/afe spacers in past vehicles and while I admit they may not increase power, they do provide better throttle response from my past experiences.

They are the same bolt pattern but I would wonder about the geometry of the throttle body with the spacer. It may have a different angle to it

Spacer.  1-800-placebo.

 

Much better things to throw money at like custom tuning or a ported throttle body (or both) to get you ACTUAL changes.
