Breaking in Hamilton 178- 60 lb springs ok ?
 

Breaking in Hamilton 178- 60 lb springs ok ? Or should I track down some stock springs ? I have not pulled the cam out of the box yet but the thought crossed my mind the other day about the springs

Should be fine ..

Do like he says and add the zinc to the oil. Verify you have oil pressure and run it. I have that cam with 62/71/12 with 5x12 and conservative fuel pump mods and the truck is a beast makes super clean power and spools great

Pretty sure they say 2 bottles of zddp+ zinc in the initial break in and one at oil change time.

I called them. They said it was fine and to use Lucas assembly lube on the cam
