It's a 273 solid cam with crane gold 1.5 rockers. I bought Summit pushrods but the lifter end is smaller than the 273's and rattles around in the lifter.

I read somewhere that LA hydraulic lifters have a 5/16" socket and solids are a 3/8"

Those pushrods are designed for hydraulic lifters running factory adjustable rocker arms. Namely 273 rocker arms.
They may be too short for your application if the cranes are factory replacements and running solid lifters.
