It seems like everybody and their grandma is goin for big block builds (I disagree with that listing calling a 408 a small block). If I was gonna do a big block I woulda got a B or E body, but I just want a lighter small block to keep that A body halfway nimble. And while a big block crate engine may be cheaper than all this stuff, I'll be making up that difference over time with the less gas I'll be using.
