    Would a cast iron be stronger than an aluminum? I'm putting a 465 behind my bigblock and the setup I bought has an aluminum. Just wondering.

    That kind of depends, but iron is a bit more ductile than aluminum, so given the same physical dimensions and shape, the iron unit would be stronger (and bout 3 times as heavy).

    i just picked up an aluminum bell from a 6.2 desiel engine on a 3/4 ton 4x4 pick up. if they use it on that it should be strong enough, but then again. i'll be puting it behind a 350.

    I'm going with a cast iron bell housing in my Jimmy, because I like the visibility and accessibility to the throwout fork and bearing. There was a time when throwout bearings had grease fittings, you don't see that anymore.

    Tommy....
    I might be thinking about going to a Big Block after having saw your rig and having heard it fire up... what all did you have to change when you went from small to big?
    Move crossmember forward?
    New radiator?
    New Exhaust?
    Fuel Lines?
    All that kind of stuff... so I get an idea of what I am looking at.

    I bolted mine right in to the SB mounts, the crossmember will have to be changed or like I did cut and weld the hump deeper for the BB oil pan. I did not have to move anything except the crossmember. This may not be the prper way, but it worked for me.
