lightest v8 for swap, sbf or sbc?

which would be the lightest setup for a v8 swap? if its available as a junk yard swap, that would be much better than a tricked out aluminum build off the shelf. im liking the fords a bit better for the forward mounted distributor but the sbc seems much more popular.

Kill a few birds with the same stone. GM ls engines are becoming available and no more distribution its all coil on plug, and aluminum. Even a 5.3 puts down a healthy kick. A manual trans will be lighter than an automatic. shop around and do some searching.

I haven't actually had both on a scale to call it concrete, but have heard that a SBC and auto(th350/700r4) is about the same weight as a 4.0l auto. I'd guess the 350 would tip a touch more but the increase in power would make up for the difference.
