Default Hemi TB does NOT fit on 2008+ 4.7L

A member on here with a late model Hemi sent me a measurement of his stock TB bolt spacing and it was about 3.1875" square. My 2008+ 4.7L stock TB bolt spacing is about 2.75" square. So it will not bolt up.

Otherwise, they basically look identical in design as far as layout and shape, etc. The hemi TB is metal and the 4.7L TB is plastic. Obviously the HEMI one is larger bore, I think 80mm. IIRC the 4.7L TB is like 74mm. I was told the stock 2008+ 4.7L intake manifold opening was 80mm. So, theoretically, you could make some sort of adapter plate to bolt the hemi TB to the 4.7L manifold, and have as large of a TB as you could possibly have on the stock manifold. The wiring harness connector would likely need modified/changed as well, but I'm guessing it is very doable, as they are both fly by wire and I think have the same wires. So it looks like it would take an adapter plate and some minor wiring change to the connecter, and then it MIGHT work. Who knows though, it may have no signal or not respond correctly...

So, I'm abandoning this project, at least for now. I may see if it'd work down the road...just wanted to share the info, I know some were wondering the same thing.
