I am running what I think is a relatively mild cam but the engine builder tells me it is what I want. It is a Webcam 86A it has 290 advertised duration and .435 valve lift with 1.1 ratio rockers( is 1.1 what bus type IV heads have?) the rockers in my heads are 914 type which are 1.3 ratio so that calculates to .514 valve lift ( .435 divided by 1.1 = a .395 lift at the cam multiplied by 1.3 = .514 valve lift.)

Thanks, Jimmy. That is a very mild cam for those heads, but it should be a torque monster with all that displacement. I'll be very curious how you like it.
