Ive been searching around but cant really find what im looking for. Im in the process of building a 455 olds motor, forged lower end with K heads. The question im after is what is the biggest cam i can run safely and reliably. Im looking to use hydrolic cam/lifters with 1.6 crane roller rockers. I want good performance but at the same time a mean sounding idle which is why i bought the headers. The boat will be used mostly for cruising with the occasional foot to the floor.
Whats the max lift i can use on the olds valvetrain?
any help with this decision would be greatly appreciated.
