Guys I have a bone stock LQ4 that I am about to put in a Chevelle. I am putting a very mild Comp Cam XR265HR into it (specs below). Question is; do I need to upgrade springs, pushrods, or rocker arms to run this cam?

Comp Cam XFI RPM Cam - 54-412-11 - XR265HR

Duration at 050 inch Lift: 212 int./218 exh.

Advertised Duration: 265 int./271 exh.

Valve Lift with Factory Rocker Arm Ratio: 0.522 int./0.529 exh.

Lobe Separation (degrees): 114

 

I would measure for pushrod length, but would your stockers work if they are correct? Yes they would. I would run the LS6 yellow springs for this cam.
