New rebuilt engine

[BLACKMARAUDER04]

So today I finally found rebuilt engines for the Marauder. They all say Mustang Cobra DOHC Aliminum engine. Is 8 bolt crank worth ($4600) $800 more than 6 bolt?($3800)
Aviator engine ($2800) is $1000 less than a Mustang Cobra engine. Which engine is “better” for the Marauder?

Whatever has the newest heads. 8 bolt flex plate is tough to find I think.

8 bolt crank is forged (OEM Cobra and Manual trans MACH1)
6 bolt crank is cast (OEM Marauder and Auto trans MACH1)

I had my 03 MM engine rebuilt. I put in a forged crank , which required an 8 bolt flex plate, which I found and purchased no problem. Chris at ADTR helped.
One member here, DanielDrives ( or something like that) dropped an Aviator motor in his MM. I can help you contact him. He might still have his damaged orig MM engine.

Chances of breaking either crank are practically nil.

Oil pickup tube and oil pan are unique for the MM, and obsolete.

What is your goal, just to have a running/driving car? If the aviator motor is clean save yourself the money and go with that. I did that swap years ago in my 03 Marauder. You'll need to swap the following over from your old motor:

Intake
Coolant crossover tube
Valve covers
Timing cover
Oil pickup tube
Oil pan
Wiring harness

I’m looking at a used Automatic Mach 1 engine. What would I need to swap over to the MM?

Bump! Any help is appreciated. I’m purchasing a used Mach 1 automatic trans engine. What do I need to change?

Oil pick up tube and oil pan, front timing cover and cam covers, oil filter housing adapter. Lower and upper intakes. Cross over tube. Not too sure about the water pump pipe compare Yours to it. Exhaust manifolds. I would do cooling mod while You're in there. Basically change over everything that looks different than Your engine.

Scroll up a few posts, someone listed swap items

That was for a aviator not Mach 1

The 3v mustang block, 2005-2010, is the strongest aluminum block. Nemak. The Aluminator is built off this exact block. That’s what I’m using.
