Re: Duntvo 30 30 cam
Yeah , that is not a Duntov 30/30 with a marking like that. Like others said, mechanical lifters and big valve lash. Rumpty Tumpty too but will idle a lot better than that 295 cam on a 108 separation 2 degrees advanced so set to 110 degree intake lobe centerline
. That Cam will idle at 1500rpm to stay running, all wrong for a truck and street vehicle.
