    GT500 5.8 swap

    So I been thinking about what upgrades I was gonna do to my 4.6 to reach 500hp but instead have been thinking about just building a 5.8 gt500 engine to swap it with.Would this be possible ?The marauder strikes me as having more than enough roomm to drop one in.I pretty much got the green light from my wife to start building one lol but need to do more research.Any input on this one would be greatly appreciated .I haven't seen anything on the forum about a 5.8 swap and yes I know this is an expensive project.Block alone is anywhere from 5-7K

    I may be wrong but I don't believe the 5.8 will fit. Wiper cowl, steering linkage, hood closure are some of the areas with issues

    An eaton swap is far more easier and cheaper to get to 425 Rwhp which is lose to 500 crank hp.

    I'm not looking for cheaper I am fully aware the engine will be worth more than the car itself

    Once again, a marauder is not a mustang. Marauder has full frame and different front suspension which also complicates fitting. I said the wiper cowl and steering linkage are issues. More power to ya if you know how to make it fit. You need to educate yourself. It would be posted here if it had been done.

    You need more home work for the 5.8 to fit,
    Is 500 HP a realistic # for you,Why not mod the 4.6 you have with a blower,Comp Cams or
    For me 345 RW/HP/N/A is crazy to drive on the streets as it is.
