Gen lll hemi install in a 67 barracuda

Couple of comments to add.

In regards the FEAD kit from Holley, it comes down to what you want. If you want to keep AC and don’t want to swap to the later K-frame and use the Holley mounts then you probably need it. There is a thread on here by @Dantra where he modified the biscuit mounts to move the motor forward and cut his K-frame so he could keep the low mount AC compressor, and others have build custom mounts, but generally the low mount AC compressor doesn’t work with the stock motor location used by the biscuit mounts. If you don’t want AC then the only issue would be the PS frame rail interfering with the car alternator which is a simple cut to make.

The other thing to be aware of is the SRV solenoid on the 6.4 intake crashes with the firewall when the motor is in the stock location. Not a big deal if you run a 5.7 intake.

And I think you will have to run a hydraulic throw out bearing if you keep the 4 speed. Far as I remember, there aren’t any swap headers that clear. You might look into it more, but that’s what I found when I looked into it for my brother.
