Hi u guys,
I am getting a Lunati hydraulic roller, 250/255 .630/.630 lift, 112 lsa for my 540. The guy at summit racing said it is made on a billet core. I tried to call Lunati but was put on hold forever, so i hung up. When I received the cam, I couldn't tell what it was. Does anyone know for sure? I know it did have a cast iron distributor gear installed on it. I tried tapping the cam lightly with a hammer and it made more of a "thud" than a high pitch, so I thought it was cast. The springs I picked are comp cams 929. They have around 150 lbs on the seat, 420 lbs open. With this spring pressure, would a cast cam be okay?
Thanks for any comments
