Really? From a truck?
With 64cc heads, you're going to be down on compression, and you've got a pretty healthy cam. But, probably enough stall to make up for it.
Probably mid/high 14's, I'd guess. Maybe low 13's with a perfect tune on a good day.
Best ways to improve would be a 100 shot, or a 350 shortblock.
BTW, not many people use the Edelbrock torque arm, and what I've typically seen of them around here is pictures of them broken.
