I am changing the cam and Comp cams says i need adjustable rockers that are $500.00 I can get a new set for a 273 compleat with push rods for $100 will they work.
you will need shorter push rods than those out of a solid cam'd 273.
The lifter cups are a lot deeper than the hyd lifter cups

get an adjustable push rod and adjust it till you get a combo of 2 threads above the the lock nut, or around 4 threads if jam nut is used, and about .030-.050 of plunger depression of the hyd lifter.

I know this is a very old thread, but god forbid someone read this and make the wrong purchase.
