I ask the question what version of Roush did you get? The R, if so you should be close to 550HP, if not then you will not. I also advise to read the small print, they are not liable for any reading except the dyno sheet you received with your engine. If you dont like it you dont accept the engine. I asked for mine in advance, they will fax it to you with the engine number. If you relied on your installer or previous owner to ensure it has 550 hp then go whine to them, it aint roush's problem, they supplied the dyno and taged the engine with result prior to leaving their shop so either the previous owner, you or the shop installing could have rejected the engine prior to purchasing if the numbers were not to your liking.

Then another person stated he had the SR version. Madmaxx says Roush rates it at 520hp, but it is putting out 507hp.
"It depends on the Engine I have the 427SR/TW and it dyno'd on the engine stand at 507 hp and 520tq".
All I am saying is if I paid for the 550hp version and it is coming up 30hp short, I would be calling somebody and asking them to explain the difference to me.
