I've seen a lot of posts about 6.0 engines out of trucks and vans used instead of the pricier 5.7 liter aluminum block LSX engines out of F bodies an corvettes. I was wondering if anybody has done a swap with the 5.3 liter LSX engine which are plentiful and can be had for under a grand. Is it worth it? I know that it would cost probably the same, if not more, to make the same amount of power that a lightly modified 6.0 or 5.7 LSX engine would make, but 5.3s are easy to come by where I live and the same can't be said for either of the aforementioned engines.
