Think the pulleys, alternator and carb cost $30K? Even the fuel injection can be had for about $7K.. here , have another KoolAid...

Oh yeah and these engines work and have a guarantee that will be honoured....
I am certainly not sticking up for Roush....but let's keep our facts straight. The 521 ci motor from Ford to which you referred is a carbureted 385-series-based motor--not a stack fuel-injected FE (which is what CSX4910's motor is). Furthermore, I believe the 511 Roush FE makes 600 HP, not 550 HP.

Roush does charge a premium for their motors--the price of their 511 IR FE is probably roughly $10k above what you would pay to a reputable FE builder (e.g., Keith Craft) for a similarly equipped engine. And yes, you could get more HP from one of the other builders from a similar engine.

In any event, what these guys are experiencing with their Roush motors sucks--as I've said before. And Roush needs to make things right.
