Eric, the Doc is obviously covering up for some feelings of inadequacy. It seems obvious to me that his aggressive behavior here has shown that, if he had the few extra dollars for an FE, he would have bought one.
Call it "FE-Envy".
Now along with these feelings of inadequacy that the Doc has, if you look at the only picture in his gallery (no pics of his alleged Cobra), it would appear to me that he has some latent homesexual tendencies.
Now back on topic. Here's a link to one of Barry R's many Engine Masters entries. I believe this one was from 2005-2006. Now, the engine cost was not disclosed, but the article is entitled Blue Collar Blue Oval. He made 752 HP with many off the shelf FE parts. Barry has consistently won with FE's. He's now building a SOHC engine for the latest challenge.
