The actual engine will go in dead easy. Its basically a pinto at the bottom anyway. You will probably have to bash the lip of the bulhead back to clear the cam cover, but tother than that it fits.
One thing to watch though, is the sump. But you would most likely be using a WCXM anyway I take it??
Oh yeah, if using a turbo there are other point to be mindful of such as turbo clearance for 4x4 mainfold, intercooler location, buring of your clutch cable!
But the engine itself goes in dead easy.
