6.4 SRT/Scat Pack – “HCI” Package – Parts Only

While we do install this package in-house we recognize that their are many enthusiasts who would rather do it themselves. That’s why we have made it easy for you to have the same great product delivered to your door. This package includes the very same parts that we install here at OST Dyno.

Our custom 6.4 HCI (heads, cam, intake) package is as radical as you can get with bolt on parts for the 6.4 motor and is an absolute pleasure to drive! We have a lot of R&D behind this package and it is proven to make insane power! With all recommended add-ons we see a 80-100whp gain on our dyno.

This package uses our famous “Big Daddy” cam. Take a listen to the awesome idle sound! Information and purchasing for this package can be found at the link below:

This package includes the following:
– OST custom-ground “Big Daddy” cam
– Custom ported Apache heads with springs installed
– All necessary valvetrain components
– Custom ported 6.4 intake manifold

Note: We highly recommend our tuning with this HCI package. We also recommend checking PTV on your own engine before installation. We have tested this cam on a factory milled head with factory valves and a factory deck 6.4. If you have changed anything on your engine that will affect PTV you must check your clearances. For automatic transmission equipped vehicles a higher stall torque converter is recommended.
