I did a 5.3 iron block motor with mildly ported LS6 heads, LS6 intake, headers, ported TB, and a small cam. Sounded good, idled nicely, and made 350/350 at the wheels through a tremec 5 speed. Torque curve was ridiculously flat and pulled to 6200. Car/engine had a lot spunk and was fun. Started as a complete pull out minus trans for like $600. Swapped/sold parts around with other platforms in order to get the correct oil pan, intake, and brackets etc. Modified the harness myself. Total outlay was around 2000 as I had the trans already.

In short, they are a good motor to choose capable of great power and enjoyment. A little more gets you a 6.0 though and a whole lot more power. Just have to decide how best to balance your goals and bank account.
