cam timing

[c12h26]

Has anyone ever advanced the cam timing on a 6bt like they do on the 855 cummins

You can time the cam wherever you so desire as long as you have enough piston to valve clearance.

Just remember that advancing the cam timing gives you more low rpm power but kills the top.
Retarding sacrifices low end torque for high end HP.
Unless somebody has done some dyno test and tune, I would just degree the cam to make sure it's timed the way the factory intended. I know in the gasser world, cam timing can vary, so it's always a good idea to check it while the motor is apart.

Advancing cam timing has an opposite affect as advancing pump timing?

Because, for pump timing, advancing gives you top-end at the expense of bottom end...

That's correct. I always remembered it because cam timing was the opposite of ignition timing, same as pump timing.

So you advance the heck outta your pump timing to get high rpm power.



You then lose your bottom end... SO advance your cam to get your low end power back.....
