Need help How much cam are stock valve springs safe for? I've never done a cam swap in a gen III motor, only old ass 350's. Wanting to put in a small cam I got for next to no $$$ then upgrade later. Trying to stay cheep for now . Got a 99 vette cam I'm gona try for a little while. Just to see. Hoping tu use stock stuff for now. Any info helpful. Please excuse dumd question I'm still new to modding these new (to me) motors. Thanks for the help.
