Let me see you baddest Eddy headed small blocks..

There's a guy over on Moparts that has a Dart with a 410sb mopar, MCH cnc ported eddy heads, 13:1, roller cam and lifters from me that supposedly made 630HP on a DTS dyno...I'm not too sure about that as he had some ring issues shortly after that when it was in the car, and has since fixed them.
His car has gone 10.20's. He's up in Washington, and I believe it was a good day, maybe 1800ft. D.A.
Car with him wieghs about 3100lbs. Auto trans, 4.30 gear I think with 28 or 29" tire. I belive he still foot brakes...MPH seems to me was around 131 and 129-130 typically.

What do you think his combo would have done with a little less compression so it would be pump gas friendly? And that is exactly where I would like my car to be if not just a touch faster to get a 9.

How much have you gotten the eddys to flow? I would like to switch to the indy heads but if I can get the eddys to flow enough I would like to keep them because I would just have to get the indys worked over anyways.
