    Try and do a search for the cam specs on here for a stock motor. Not sure that I've ever seen them posted (they are out there for the Vortec springs) but that would at least give you an indication of what the springs were dealing with stock.

    As cheap as standard springs are though, if there is a question as to whether they will work, I'd just buy a set of whatever the cam company says you need for them.

    Read the info that comes with your new cam. Most state that there is NO warranty if you don't install the correct springs that the cam maker recommends.
