7.3L Godzilla Fox Body Swap | EP: 1 The Mock Up

← Swipe For More 7.3L Godzilla Engine Photos →

Within this article, we will cover some of the initial mock-up procedures that Landan and Scott encountered in our 1992 Calypso Fox Body project car. Even though this larger engine is designed for the truck chassis, we wanted to see what is involved with this Godzilla swap in our Fox.

Ultimately, we do want to keep this project naturally aspirated. This way we can make this mock-up as simple as possible within the factory engine bay without substantial modifications to the chassis.

Team-Z provided us with one of their tubular K-members designed for this engine. The included motor mounts bolted right up and allowed adjustment when lining up the K-member. This kit allowed for clearance between the oil pan, the cast-iron block, and the exhaust manifolds.

This project car previously had a 5.0L Coyote installed that was equipped with a hydro-boost brake setup. We opted to remove this and install a 93 Cobra Mustang vacuum booster to check for overall fitment issues that could arise. We really wanted to cover some of the common chassis setups that most people will be using on the Fox chassis.

We mated the Godzilla engine up to a 4R70W transmission out of a 1999 GT Mustang. Since this engine shares the same bolt pattern, it will bolt up to the block without any issues. Next, we removed all of the factory suspension out of the chassis to prepare for the Godzilla to go in.

We still have a few more things to do to finish up the mock-up, so make sure to subscribe to our newsletter so you can be up to date with the next update and video we release on this subject!
