Did you not tell SH what you were borowing their shop for and what they were going to be tuning? I'm suprized that they didn't inform you with all the tunes they've been through. I didn't want to be the one to ruin the excitement not to mention I was hoping you guys had some sort of trick up your sleeves. Both the 392 crate and 426 use the same cam and they both have valve releifs cut into them with about .100" clearance on the ex and about .080" on the int. That's not to bad really, but Mopar doesn't recomend using it with flat tops anyway. Sorry to hear the disappointment, hope you find the right numbers cam.
