Throttle body top mounted ?

[ACII]

Hy together..

i would like to get a more traditional look for my ls1 setup :-)

On the net i saw some setups which have the throttle mounted on the top of the engine...almost like a carburator.

Finally i want to install 2 throttles (or 3 smaller throttles) on the top.

I would use and adapt an intake like this one =

The plan is to close the original opening on the side and weld in 2 or 3 mounting plates for the throttle on the top of the intake manifold.

Furthermore i would like to use all the sensors, but i have no clue how to handle the mass air sensor .....even more if installed 2 or 3 throttles..
Any ideas ??

What do u think about this plan ??

Thanks a lot
