Throttle body orientation

Hi!

Upgrading my already LS swapped 1992 camaro from LM7 / 4L60E to LQ4 / 4L80E. Since lm7 was DBC, I was able to keep the truck intake and had just enough clearance to close the hood. Now LQ4 has a DBW, the TB itself is little higher and cant close hood anymore. Thinking about making a spacer/adapter to turn TB 180deg, upside down. Would be there any issues in engine performance? I have seen some pics procharged Ls engines, with TB-s upside down...
I know the right way to go would be ls1 intake and re-routing cooling and front accessories, but since i have all perfect set-up from LM7, then I would like to keep it. And also here in Europe it is not so easy to find LS engine parts, so its also all about budget :)

Thanks

Why not just use the cable TB on the LQ4? You can make the LQ4/4L80 work with the LM7 cable TB PCM/OS with segment swaps and tuning. Then you wouldn't have to change the pedal and add the TAC module too.

Shouldn't be a problem.. Fairly certain some old magnacharger kits had you turn the throttle body upside down too.

Can't find it right now but have a friend who was Chip Foose's main tech. He actually made a traditional style looking "carb" intake with a DBW on top. Put a regular air filter. Looked like it was carb'd.

Here is a DeLorean I just did and it has a 180 to the throttle body. Works great. Air is much easier to deal with than air/fuel combo because fuel will crash into a wall and puddle. Air doesn't. Much more "bendy". ;)

@2xLS1:
Promised to sell the full lm7/4L60e DBC turn-key kit to next caprice guy. LQ4 is also full drop-out kit from 2007 Savana, so why not to use it in a stock setup
