I'm building an engine very similar to this. I have decided to go with the factory 068 cam. It should be very easy on the valve train and should allow me to run pump gas with the stock 10:1 compression ratio. I am running a 744 cam in a 421 engine with 10:1 compression and 670's. I think the 068 cam would have probably been just as quick though. It does run good with the 744 but I think there would be more power to be had with a summit 2802 cam or something similar.
However, I don't think you could go wrong with that Crower 60916 cam either. Just use some big block Chevy rocker arm studs and nuts to change the valve train to an adjustable valve train. It should be a good runner.
