BTR only has their Truck Norris Godzilla cam at the moment. They did tell me that more were designed, but nothing has been tested and apparently cam cores are hard to get.

I am kind of leaning towards the MAST HO Godzilla cam. All of the MAST cams have the VVT locked out, which is what I would prefer.

I'm betting the MAST HO Godzilla cam was based/tested around those heads you acquired. That would def be a decent choice.

After going back and forth and exploring as many cam options that I could find, I decided to go with a cam from Mast. It is their Godzilla 7.3 HO cam and the full specs can be found here:

The torque and power are represented in red in the graphs above. It really seemed like the "goldielox" cam. It loses a little torque below 3000RPM, but above that point it makes more torque everywhere, including the stock cam. It doesn't make quite the peak HP numbers that the bigger, Godzilla 7.3 GT cam (green lines), but it is darn close, without giving up significant torque down low.

These numbers were generated with the CNC ported heads that I have and a stock intake manifold.

Comments and suggestions are always welcome.

Looks like a great choice!
Those poor rear tires. Lol

Seriously, this car is going to rip with this engine. Dear lord that torque curve.

Honestly, I will be disappointed if it doesn't run as good as it did with the LS supercharger combination.

Don't hate me...I guess Ford engineers decided to use readily available parts for the Godzilla engines. The lifters are exactly the same as LS lifters, so I decided to upgrade them to a high quality part.















Given that the current LS3 in the Cougar probably had a lifter failure, I did not want to take a chance.
