I'm removing a Holley that I installed on my 69 GTO 400 a looong time ago and I am putting a Qjet back in its place. The bolt that holds the choke tstat housing on the factory intake has been broken for longer than I can remember. How deep can I drill before I break through into something important? I plan on drilling the bolt out and running a blind tap to recreate some threads. Thanks in advance!
