Does anyone know if the crank that came in the Marauder is a six or eight bolt crank?

I was wonde3ring whether the cranks were forged or not, and if they were 8 bolts. I saw a picture of the crank, and to me looked like 6 bolt.... any idea?

Looks like the Marauder motor may not have a stock cobra forged crank (which are 8 bolt). That's what I am hearing from my sources. I think this means that when you go to a forged shortblock you will need a 800 crank.... I wonder if the Mark VIII has a forged 8 bolt crank (Dennis?)

The Cobra, Mach 1 with manual trans, and trucks are the only forged cranks with 8 bolt flywheels.

Marauder has a cast 6 bolt crank as does MK VIII and Continental.

There is another thread on this subject:

Thanks I didn't see the other thread, the stangparts pic is what made me wonder. I was looking to do a 4V conversion in my mustang, ang thought the marauder motor would be a good place to start, although if you add a forged crank (575 from Kar Kraft) it started to equal a new 4V motor (OK not quite).

I don't think the crank is the weak leak in the modular set up, so it may nit be an issue, at least it wasn't in my old car (Sarge's new car).

Again thanks
