Maybe im just imagining this but i remember someone saying theres a way to switch between different pullys without the pully puller once youve installed it once. Is there such a product out there, if so where can you pick one up. Also another ?, how hard is it to replace the belt when your installing a new pully. Bottom line im looking to get a 3.4 fairly soon and would want someone with puller to help me out, for $ of couse. I'd be putting 180 stat, plugs and belt with the pully, the only thing id need help with is the pully of couse. Any info on any of this stuff would be great. Thanks
