Small block pushrods with hydraulic cam.

My plan is to use the hydraulic lifters and magnum pushrods with the stock 273 rockers and adjustable rocker arms. Is there another problem with doing that?

Magnum pushrods from a mopar magnum engine are way shorter then a LA pushrod due to the taller hydraulic roller lifter....

if you are talking about compcam magnum rockers for LA engine...just get the correct length
