Cam shaft in my 273

Here's the deal, I bought this 1965 273 HiPo motor from a close friend who owns a auto shop. He built it for a customer who has deep pockets. They finished the motor a trans rebuild and installed it for the customer. Customer came , picked it up and returned the next day and said it wasn't enough power for him. The customer ordered a new big block crate motor and trans. the next day. My friend installed new engine and trans. customer picked up the car and was happy. My friend asked when he was going to pick up the 273 and trans. and he sayed just keep it I don't need it. My friend called me and asked if I wanted to buy it and I said we could talk about it. When I went in to see it I asked what all had been done and it was pretty much the works balance, hone, decked bored. The one missing piece we could never find was the cam info. He couldn't remember what they got for the motor except it was a solid lifter and pretty good size. I bought the motor and trans and have it in my car now. I would like to have your guys opinion on what you think it could be close to in size. It idles in neutral at about 1000 rpms and about 850 rpms in gear. The power band is about 3,000 to 7,500 and still pulling. The timing is at 30degs total advance. I would just like some guesses.
Thanks
