Thanks for the math AJ. Now that’s theoretical (if not actual) cruise rpm is established, a better cam for the idea of some ability to cruise in can be sought after. 70 MPH would be about 2474 RPM’s? And 70 MPH is about a good speed on the interstate.
Let’s round it up some. 2300 - 2500 cruise RPMs.
The best cruise cam would have a listed starting rpm below the cruise so the cam starts to come into play. With the combo and cam, efficiency’s the goal. If the cam is to big, the engine and car act like a pig in throttle response, mileage and generally the feel of the car as your driving. When you press the gas pedal down without kicking the trans gear down, the car feels lethargic and may even lug and chug until the combo becomes efficient again.
I think the cam size first given to you is really good until you get into overdrive. Otherwise it is an excellent hot rod cam. It’s gonna make some really nice power.
Just not a Hwy. cruiser.
