LQ4 bellhousing bolts
I have a LQ4 engine out of a 02 silverado I am planning on using a turbo 350
on the block one of the bellhousing bolts is not drilled just wanted to check
and see if there would be any problems drilling and taping the block
thanks

It is the water jacket IIRC.
But it will be OK if you leave it out, I remember running a BOP TH400 behind a 350 for a couple years using only a couple bolts with no adapters whatsoever and I never had any problem....
I know that was a terribe hack job, but then that's what I had and I used it, and even to my own surprise the thing held pretty well. So with only 1 bolt missing you shoud not have any problem.

I know it's an old thread but maybe this will help to someone:
Yesterday, I drilled a 6th hole on my LQ4 with 8.5mm drill bit, 17 mm in depth and I didn't reach water passage.
Then I cut a thread M10, about 13mm in depth.
Now TH400 fits perfectly with all 6 bolts and 2 alignment pins.
