Brent Just look at the end of he push rod, If it has a hole through the middle it's hydrolic, if solid they are shell lifter that look like hydro's without the guts. Hydros are .300" taller the the shell lifters but look the same. How long is the pushrods? 9.157 that's a shell lifter but has a little play to adjust. Rick Lake ps I switch my motor over to real hydro lifters, you need to use SB ford lifters and hollow pushrods. If in doubt ask Joe or George.
