Yes it's a hydr cam - I forget the specs, but I think it's PS 474/474 (P#312-P4452993 on JEGS), if that rings any bells. From what I hear Crane or Comp seem like the cams to go with nowaday. What needs changing to use a roller cam with the old J heads? I know there's much info here about that, but is there a Q&D ans on that?

OK I think that block from the factory has a hydraulic roller cam. If it is then it's an easy change. If you don't have that many miles on that engine you can reuse the lifters and just replace the cam to the tune of $305.95 from summit racing COMP Cams 20-810-9 and you must purchase the correct valvesprings. If you want to change a flat tappet engine over to a hydraulic roller then you are looking at lifters (cheapest ones I saw were Hughes engines retrofits $399 and a cam at 305.95 and springs. The engine block must be checked for clearance for the link bar with the retrofit hydraulic roller and pushrod clearance, length must also be checked for both the cam change and the retrofit. It gets a little confusing and hard to explain when I'm typing it out but it is easy to explain face to face. Hope this helps!!!
