Will 90mm TB work on 105mm High Ram?

[tvanlant]

I'm looking to purchase a High Ram for my LS3 soon. I may want to upgrade to a 105mm throttle body in the future, but plan to use my stock 90mm LS3 throttle body for the time being. Will the 90mm throttle body work with the 105mm intake lid? Wasn't sure if the larger diameter o-ring would seal properly on the smaller throttle body.

I think it should work fine. The Holley Hi-Ram does not use an o-ring at the TB, but uses a gasket. The gaskets can be used either with the 90mm or the 105mm TB. Andrew
