Default Re: Which New Cam,,,330 or 340

I have the IB330 cam with big intake valves and 5.5 head,Zenith. I used this engine with a reground touring cam for a while and when I added the 330 it made a big difference in hill climbing and speed aginst the wind when I drove out west.It was noticeably better in overdrive as it is a torque cam,not high rpm.

I recently put on an English Stromberg 97 and it runs smoother and has more power. I highly reccomend the 330 for a stock Zenith or downdraft.The cam definitly adds more than a downdraft carb by itself, and then you can add that later if you wish.
