Cashburn is right. I know even though they use Holley carburators, Roush either specifies certain jets, springs etc or modifies them theirselves. Their billet aluminium spark plug wire holders are pretty nice, the devil is in the details. If I were going spf, bdr, quality replica I would not have any heartburn spending the extra for a Roush. If I were buying a used cobra for $20K and the engine went out, then I would probably take a different route. I knowed I called Roush on a distributor question and they promptly returned my call and discussed in detail how the advance was set. I have never had to use it but their warranty service can be slow at times. Their warranty agreement is also squirrely if you read in detail they only have to warrant up to $5K, although from threads on this forumn they have warranted engines repairs out of warranty with almost a full free replacement. Unless the abuse was excessive and obvious, they will stand behind their engines.
