the end of the new cam box has.. 50228 Buick 215-340 compu-pro hydraulic cam (250-HDP). my invoice has.. Perf, cam kit – level 1. i just told them i wanted the closest thing to stock as i could get. he said he couldn’t get the exact thing but this cam would be close. my stock springs check out good so they reused them. what can you tell me about this cam? should i use something else? i didn’t talk about other cam options with him.
