I am changing cams and I am seriously starting to think about going roller, I have a set of roller lifters out of a 5.0 in a truck, I haven't looked them over yet, but can I use them on a new cam, or is there something that I need to check? Also will I need shorter pushrods, or will the current pushrods work with a cam with the reduced base circle use the same length ones? ------------------

You can use the old lifters, but at $130 for a set of brand new FRPP units why would you?
Yes, you will need substancially shorter push rods.
FYI, you can only use OEM style hydraulic roller lifters in a roller block.
If you have a standard block you will need to use the conversion style lifters which are about twice as much.------------------

Alex, can't you use those o.e. roller lifters in a older block with a reduced base circle cam, or something like that?------------------

Not to the best of my knowledge BL.
The tops of the lifter bores are taller on the later blocks.------------------
