Goodwin Competition made 1200+ HP NATURALLY ASPIRATED w/ an Indy -1 head on a dragweek motor built for nitrous. You believe that?  In reality, I think it would take something like a Predator or a good B1 MC or PSO to do it. Or whatever the biggest Indy conventional heads are now...600-13 or something like that? I find that 1200 NA from a -1 head hard to believe. Im not saying its not true, but wow thats hard to believe. A -1 head can flow 400cfm, but still hard to believe. Now 1200 with nitrous, yes that i will believe all day long Exactly. Some guy all over the Mopar pages on FB has a white Duster he's putting together (writing checks) for drag week, supposedly, and loves posting pics of it. Gets real butthurt when anyone questions it. Goodwin builds some awesome stuff, but I wonder what they know about making power w/ -1 heads that NOBODY else does.
