Hey guys

Not sure what happened here, but when bolting up my surge tank to the intake (Blue thunder MR 2x4)the bottom bolt stripped out the intake threads!!!! It was wierd, I was using a hand socket driver (not an air ratchet) and I didn't have any resistence. The bolt went right in but kept spinning and never snugged up. I pulled everything back off and sure enough there were aluminum threads on the bolt!

So basically I need to retap the hole with a bigger thread, this isn't a big deal, but a few things I need to know before I can call BT on Monday are:

1: Is the depth critical on the lower bolt hole? As is, the depth is only about 1/2" deep, but could I drill a bit deeper since I will have to used a hand tap instead of a CNC bottom cutting tap. Or will I break through into an area inside the intake? How much room do I have there?

2: Does anyone know right off hand what size that thread is, and the next size up that I should tap?
