i just installed the crank in my 350. torqed it down 70. when i tried spinning it it didn't move freely. bought the crank at autozone . the guy at the machine shop said their cranks are not machined to the best quality, and the journals may not all be the same size. he also said the journal caps go in a certain order from front to back, how can you tell. this is not the same shop where i had the block done, they didn't do it right. should i take the crank back or have this machine shop check out the block and crank. thanks for any help!!
