CSX3170 didn't post the specs but he is on the forum so you could send him an email. It's a big motor with high compression so a bit of a different animal then what we are building. I talked to Keith and he said he has done a few Victors and milled the carb flange .500 to make sure everything clears. Said it would definately kill some of the low end tork and build more power up high and that's what I really want so I'm going that route now....
