stock 5.0's came with a hydraulic roller cam which is user friendly low maintanence. the lifters are heavy and this limits rpm range. Solid rollers require alot more maintanence and some stiff valve springs but you can rev them extremely high.

The pre 85's 5.0 had solid lifters.
Dont even think about solids. Just get roller its better.
No, they didn't. They had flat tappet lifters, but they were still hydraulic.

Hydraulic roller will be fine for anything up to 500 horse and 6500 RPM. Any more than that and you'll want to think about changing to solid.

solids are a better cam in general, but you would have to change the springs ($300) every 12-15k to be reliable.
