after talking to the shop he said it was a cast cam. i asked him who's cam it was but because i was asking other questions he never said. he did go on to say that the cams he gets are either cast or billet. with that being said i felt ok about what lifters should be used. he wasnt happy that i brought the liters he supplied back which was the second time they were wrong first time they were the right design but were hydraulic. i took him one of the original lifters to show him and a sheet showing why the type i had needed to be used. he just looked at me and said he'd call me when he got them.
