A/C Compressor Mounting with Car Engine
There is a wrinkle to this that you should probably be aware of.
Holley's notes show this image with the dimensions for a non-VVT car and VVT car belt spacing:
The trick is, I believe the '09 and '10 5.7 car setup use the non-VVT belt spacing and do not match the later 5.7 VVT belt spacing. This based on part overlaps for AC compressors, water pumps, PS pumps and alternators. As an example, the PS pump for a car 5.7 is applicable to an '06-10, even though the '09-10 is VVT.
Due to this, I think getting the AC compressor you have bolted up will not be as simple as just moving the motor forward 1.75" to match the Holley engine placement.
When I was looking into this, it appeared that the TC cover was the same from '09-13, which implies that maybe an '11-13 FEAD might be able to be swapped to move the compressor out .48".
The other thing to be aware of is the PS pump. Later 5.7 cars went to electric power steering or an electric pump, so the only VVT motors with a pump are the 6.4's up to 2014 (I think) and maybe the HC's. The point being that if you use the later belt spacing, the PS can be a little more tedious or expensive.
