Personally, I would go the route of the 5.3 LSx engine. The old sbc engines are fine but the LSx platform of engines makes more power/torque and wayyy better mileage. Since you're spending money, do it right. It will be a good winter project. Take a look at some of the build threads on here, the swap is not that hard at all, it's just an involved process.
