how bad of a job is it? im tempted to do it myself. anybody have dyno charts of the 6.1 and the comp cams xfi ? or know where to get them? I want to see rear wheel power, not the flywheel crap.

 

..I dynoed with a bunch of hemi guys early this year... I dynoed at 335hp with a 6.1 cam, another guy dynoed with the xfi 260 at 330hp, and he had headers (I didn't), and he dynoed with drs (I dynoed with stock 20's)...but he did show a flatter power curve while mine peaked...

 

how exactly is the new cam to be intalled? does it matter on our motors? certain position?

 

we prefer the 12 o'clock position...just spin it a few times to push the lifters all the way out...pull out/push in the cam in the same position...just don't drop the timing chain...
