The crate says “FRAGILE / HIGH CLAIM VALUE” — what it actually meant was 7.3L of naturally aspirated Godzilla fury.

We just safely delivered this 675 horsepower monster crate engine right to our customer. The destination? A lightweight '88 Fox Body Mustang.

Let that sink in for a second:

7.3 Liters

675 HP

Shoved between the fenders of an ’88 Fox Body

That chassis has no idea what’s coming for it, but the streets definitely won't forget it.

Big thanks to our client for trusting us with the delivery of this absolute unit. We can't wait to hear this thing fire up for the first time. 🔊
