considering putting a atlas engine in a square body pickup as i heared some good stories about the relyable power they make when fitted with a turbo, i keep my eye on this one

cool idea about the fiat oilpan
so you now need to machine the whole bottom part of the pan till theres only 2 inches left up from the gasket seal part and leave the dustplate for the clutch then make and weld a flat piece of alu plate over the hole
do you still need to put the stiffener ribs to the dustplate back again ? they look kindah in the way of the new oilpan
is the casting thick enough to just make a bunch of treaded holes around the circumference make a gasket and bolt the flat part onto the original cast part

thinking about all the machining needed
it might be simpler to have that 2 inch pan part cut out of a 2 inch sumtin thick piece of aluminium billet complete with the bottom the holes for the fiat pan and a seperate dustplate for the clutch bolted to the back of it and call it done
might even be able to leave material in the cavity as a studgirdle inside the pan for the mainbearings with the mountingbolts going trough and through.... if it wasnt for the brackets for the accessories on the side you mentioned the cad file shouldnt be THAT hard to make
