Aviator vs. Marauder...

[PonyGuy]

Excuse my ignorance, please...

Anybody know the difference between the Aviator's engine and the Marauder's? And the Mach I's, for that matter...

All three are 4.6 DOHC, and they are all rated about the same horsepower and torque. I read somewhere that the Aviator had a slightly different throttle body and intake set-up, but the source was not reliable enough for me to believe. Supposedly, the Aviator had a better torque curve because of the intake system's difference.

Thanks for any information... or refutation.

Pretty sure it's the same basic engine, maybe with differences in tunes, along with some minor exterior components to fit one vehicle vs another.

I believe the Mach 1 engine from a manual trans car has a forged crank.

Aviator has an extra gear, 5 speed auto. Do not know about engine.

Thought the MM engine was the automatic Mach 1, with Aviator cams.

Mach 1 manual has forged steel crank and passenger side intake with dual bore throttle body. Mach 1 auto has no forged steel crank but slightly more aggressive valvebody (basically Jmod from factory).

Aviator has the same "longblock" as the Marauder but uses a large single bore throttle body.

Mach 1 auto, Aviator and MM all have the same longblock setup. Only differences are the intake systems.

I've always wondered the difference. I have a 2003 MM and a 2004 Aviator. The odd thing is they both have the same HP rating, but the Aviator does not require premium fuel. I could never figure out why.

Steve Babcock explained at MV-9 that the 2003 has only one NOC sensor while the 2004 has two. Since the 2003 is "guessing" as to what the second bank is doing, it cannot retard or accelerate the firing as quickly as the 2004. Therefore, the 2004 can operate on a lower octane rating.

I think the pulley's might be in different locations per application. I know when I had a replacement block from Ford we had to switch some parts out and make sure they where based on a Marauder Pulley configuration IE Alternator braket/Pulley, etc.

Really? I have an 03 Aviator and it requires premium just like my 03 MM. Did I misread the manual or sticker on the fuel cap???

I guess that explains it. LOL!

I could never figure out why. Thanks for that info. Mine is the reverse. The Marauder is an '04 and the Aviator an '03. They both require premium. I put 93 octane in the Marauder and 89 in Chip, my Aviator.
