1988 Fox Body 7.3L Godzilla Swap

[ca_preston]

So my dad bought a fox body without talking to the crew. So here we are, getting geared up to put the Sema thrash on this 1988 Fox Body Mustang.
To be honest the car itself is in pretty great shape underneath with a small bit of rust in the engine bay.

The plan for this car is to use Detroit Speed suspension, use a wide body kit, put a 7.3L Godzilla motor in it, Forgeline Wheels, and refinish the interior to be a pro touring monster!
I'll post up more as we start to dig into the car!

More Fords makes for a better read!

Very cool!! I've been waiting for someone to grab one of these motors and swap it. How well would it fit in a first gen, haha.

Cool project!

Im dropping in a 427 LS into my 69 Fastback, wanted a Godzilla, but there is little to no support for them so everything had to be custom.. I think the 7.3 will have legs, once the aftermarket catches up..

I’ve been skeptical on this engine but it seems to be taking well to the Ford community as far as hype goes. I’m skeptical because that GM 8.1 did not do well in the swap community. The biggest issue was that big oil pan which doesn’t fit much else and no one made any retrofit oil pans. Hopefully this engine sees a better future than that GM engine.

Let’s see some progress!

People are already figuring out how to get the cam/crank signals for Holley EFI, so it's a matter of time before they are everywhere. So cool you are blazing the trail. What is your plan for the oil pan and headers?

We're doing some development work with Indy Power Products. They will be offering an oil pan adapter to do a lower profile option. https://www.indypowerproducts.com/shop

We had it running yesterday on an ECU Masters BLACK unit. Sequential fuel, but wasted spark as the ecu only has 6 coil drivers.
Strangle enough the crank reluctor is a 60-2, while the cam is a 4 tooth (two long, two short). Fortunately we found the ECU Masters had a cam and crank profile already available that worked.
The only issue is the throttle body does not output a variable voltage signal. It transmits a SENT digital signal, which we’ve found not many support. So I’m printing an adapter to put an LS3 throttle body on it for initial testing.

Very nice! I was reading that there is a variable oil pump or something in the Godzilla motors that is electronically controlled. Is that something that the ECU you are running can handle? Curious if that could be made to work with Holley?

[marolf101x]

The motor going in the Foxbody has the Indy Power Products front drive kit and oil pan. It replaces the OE oil pump, which is located in the pan, to behind the front cover.
This allows the pan to be extremely shallow, and negates the need to control the variable pump.

We're back and 9 weeks away from the SEMA Show.
We've got a buttload of work to get done on the Foxzilla before we get to pain.

Wow, you guys aren't messing around! This should be a beast!

[ca_preston]

We try to take everything we build seriously!
It should be an absolute unit on the track... thats if we can get traction haha

[pinebox]

Impressive build!
Interesting how you have used the front rails from the older car to get the DSE front suspension in there. Very cool!

[ca_preston]

That is one thing that is a bit interesting with the DSE kit, is we had to blend in the front frame rails to make it work.

That's going to be a brutal car. I'd love to see Ford to a short deck version of this engine That would max out around 6L or so. Coyotes are great engines, but they're gigantic physically and very expensive to build.
