The biggest problem with these engines is there are not a lot of aftermarket parts for them. No one has a real cost effective cylinder head available or good rocker system with out spending a chunk of change. Most people want 20,000.00 for an old engine if not more. Most people do not want to spend 30,000.00 to 40,000.00 on an engine either. You can also build a regular 800HP FE these days for 25,000.00 that has all of the latest trickest parts available. I think it is more about the uniqueness of the engine than anything. Just my two cents worth, Keith
