Hey Dave
I know this an old thread. I don’t know if you are still looking for info on this cam. I had one in my GTO back in 82 and it IS a hydraulic cam. The lift IS .485 and the duration is 300. The anti-pump up lifters are the best hydraulic lifters Isky had (very desirable)to help smooth the cam a little a low rpm. You mentioned you were interested in selling the set-up. If you still have it are you still interested?
