I used your cam numbers above, but just plugged in a roller profile instead of a flat-tappet profile. The Crane Cam 325-2S-12 hydraulic roller piece produced similar numbers.
What Hyd roller cam was this and how would you ever keep the drive line together with those #s?
The tranny should hold it, as should the rear end. U-joints are a weak link in the late 70's stuff. I'm not so sure what the transfer case will take. Someone else will have to chime in here.
Please correct me if I'm wrong here but I'm assuming that a hydralic roller, with published specs similiar to a std hydralic cam, will produce quite a bit more HP and torque because the lobe ramps are steeper from .050, over the nose and, back to .050.
I'm starting to lean towards the middle of the three Crane hydralic rollers now. I think it's the same one Brad listed above. From my research, Crane produces the only hydralic roller for the 460.
The more aggressive roller profiles will make more power at the same overall duration and lift. It results from the better airflow characteristics at partial lift. You also get a free couple of HP in the reduced parasitic power loss. The downside is the overall extra cost, but in the dollar-per-HP catagory it's a pretty good deal.
