I don't know why he didn't like it, he didn't give me any details. I also don't know why the Bullet cam was installed at 4 degrees retard, I asked him and he couldn't remember why he did so. I just looked at the Bullet cam card again and it said to install the cam at 102 intake centerline so with an LSA of 106 perhaps that's why it was in 4 degrees retard? Also, I changed cams because I had a roller lifter tie bar break late last season, which allowed the lifters to rotate in their bores with did some minor scoring on the cam lobes for that cylinder. I thought it best to change the cam.
