Post BPS Proformace Cam
I'm on the fence about getting the billet performance cam for my MB 4400 HDR. The motor has 80hrs on her, and the only thing I've done is upgrade to a slightly bigger oil cooler that's it. Would like to hear from anyone who has done this and/or any pros or cons to doing this. Figured I could get a little more out of this amazing motor and have some money to spend... what do you think?

Depending on which cam, you will see some differences. I personally wait till the case starts leaking.

You should ask for some specs and an explanation of what they mean with your builder. I like to use smaller Duration camshafts with a Tighter Lobe separation to increase the overlap where its desired for the mid range torque pull that us mudboats really appreciate. That on/off the throttle is where we need them to shine.. Also on a hunting motor you want easy lift and closing ramps to keep the valve train stable.
Note if you put a cam without heads sure you will feel a boost in power, BUT limiting the airflow with the cylinder heads is the choking point.
