[QUOTE="black03, post: 4900050, member: 4037"] We have seen over the last few years plenty of twin screw cobras make over 700rwhp on the stock block. I think 800-900 is pushing it way past the limits of the stock pistons and rings. Thats why most guys making over the 700rwhp range have done some engine work such as pistons to make it handle the power and higher boost. If you run the 3.4L you do not need to rebuild the motor. Because you can run the 3.4L at a boost level thats still within the limits of what the stock block can handle. If you plan on making anything over the high 600-700 range then I would recommend getting a shortblock. Yes, the stock block may handle 700+ but thats like saying you can drop a glass bottle and it will never break because it may and at anytime. I mean there are guys with ported eatons who make a lit less hp than 700 that had engine failure and there are guys that make 700+ without any issues. There's several things involved. How was the motor built from the factory, how aggressive of a tune do you have, how much boost are you going to run, what type of fuel are you using...ect.ect. So, My personal opinion is you can run this blower or any other blower made for the 03-04 Cobra on a stock block within limits. Hope that answers some of your questions or concerns.
