'Godzilla' 7.3 Ford V8 Hits Nearly 800bhp At 7600rpm, Still Very Much N/A
There’s a new member of the Ford crate engine family: the 7.3-litre pushrod ‘Godzilla’ V8. It’s intended as an alternative to a big, torquey diesel engine for pick-up trick owners, as reflected in the figures - the iron block unit develops 425bhp at 5500rpm, and 475lb ft at 4000.
With a bit of work, though, you can change the power output and the character of the $8150 engine dramatically. RevEvian, having already liberated 500bhp from the 7.3 with some simple modifications earlier this year, has been keeping tabs another Godzilla project run by Team Z Motorsports in Detroit. There, the V8 has been pushed to 790hp at 7600rpm.
Quite a lot has changed to get this engine - which Ford originally developed for the F-250 Super Duty - to those figures. It now has a ported cylinder head full of new stuff, Wiesco pistons, aluminium con-rods and a rebuilt bottom end.
It’s still very much naturally-aspirated though, and that’s not the limit of this engine without bringing forced induction into the mix - apparently, with further tweaks, it’d be good for around 900.
This 7.3 won’t stay N/A, though. Brian Wolfe and the team will be adding a 3.0-litre Whipple Supercharger, with a targetted output of around 1600hp. Yes, nearly four times the original output.
It’ll be stuffed into the bonnet of a FoxBody Mustang, which isn’t as ridiculous a transplant as it sounds - the engine is actually a little narrower than the widely used Coyote V8.

Nothing sounds better than a screaming 800bhp 7.3L V8 engine!
the iron block unit develops…… 475lb ft at 4000.
What the fuск does that mean? 5Nm? 5000Nm?

That’s a question you should ask google

For anyone who likes their numbers in Si units (you know, the ones that are globally standard and used in every engineering and scientific application) rather than the gobledegook provided:
475lb ft is about 640 Nm
425 hp is about 315 Kw
790 hp is about 585 Kw
