I don`t know about these cams either, but honestly, I would go with a smaller cam. Reason being you get into the sure enough thick mud, even so you have the advantage of a 5 speed so you can rev it high as needed, it`s going to lug the engine due to the lack of torque with that much cam and lugging it is the worst thing you can do to a engine. I would use a cam that had a power band that started at 2000 at the lowest. Summit sells the 80 buck hydraulic cam and lifter sets and I`ve used many of them without issue.
A cam with duration of around .224 @ .050 is as high as I would go. But thats just me and my opinion. being I`ve had experience playing in the mud with big cams I learned a little bit from it. If you were running a 383 or a 400 I would run the larger cam without worry.
