Don’t forget the option to use a low mount AC compressor on a VVT motor and that the 90 degree adapter works with no issue.
For me, the ability to use the stock AC compressor and not cut my firewall for the 6.4 intake was enough to push me to go all Holley. Add that I already had a spool mount k-frame made it all the easier. And I got in before the headers were discontinued. Now that the headers are discontinued and others are getting the 6.4 intake to fit with smaller adjustment, not sure what direction I would take if I had to choose. Still haven’t seen a clean option for the OEM compressor yet with the other options, but maybe i missed it.
