[Fitting 4.0 Thor into a 90]

Hi all, Thinking of fitting a 4.0 V8 Thor engine out of 1 of my P38's into my 90 which is currently fitted with a 3.5. I see that Devon 4X4 have done it to one of there project motors. Would any of you guys happen to know if it's easy enough to do with the wiring ect ect.

thanks in advance 

[P38]

Hi all I have a couple of P38 V8's and before I try and sell them off now I have what I wanted off them, Am thinking of building a winch buggy but what I would like to know is if the chassis and axles would be strong enough for the task?????

 

Any help or advice will be greatly appreciated

 

Thanks
