Those LSX engines are a great platform.

i was watching a great show "How its Made".... exotic cars... some amazing engines on there! the bugatti W16 and W12 are fasinating but an engine that caught my interest was they were building the porche 918 hybrid car everyone should watch that show its an amazing piece of technology the engine is a 4.6 V8 with exaust in the center of the V naturaly aspirated 680hp and it looks like it would make a neat boat package anyone else see that episode?
