I know im gonna catch shit for this question but i gotta ask because im impatient. i have the money right now to buy some camshafts and springs. im looking at getting a set of brian crower 272/272's. now my questions, first, if i get these can i run them with stock cam gears or will i need to change cam timing right away? next, will it cause any damage if i run these without tuning? i have all intentions of getting cam gears and an aftermarket ems when finances allow. but for now id like to slap these in.
thanks in advance
