Anybody running a Comp cams 268?

The 268 is a good cam. Makes for a great sounding exhaust. You will see a nice power gain. On the converter a 2800 stall is plenty. (don't know what you currently have) as this is a fairly common build on dodgetalk. Ane 400 FWHP should be about right. But you have headers and such so I'm guessing it will be slightly higher.

On the valve springs pick up 16 6.1 exhaust springs and install them on the intake and exhaust valves of the 5.7 and you will be good to go. You will also need to run 6.1 pushrods, as the 268 has the same base circle as the 6.1 cam it will help keep pushrod length in check, and minimize rocker noise. (same as a loose rocker on the 318)
