I'm sure there will be a big power difference from the 5.3L! The 5.3L was probably making about 300-350 rwhp (just a guess) with the cam and such that it had. The 6.0L with L92 heads and LS3 Intake and Comp Cam should be making 460 rwhp! The heads are not decked or milled, PTV clearance is good with this cam but I have heard that some cams can have issues with PTV. I had seen this cam used in an Fbody with an LS2 and these heads so I knew I would have PTV clearance with the LQ9. The compression is probably around 10.8:1 or 11:1 depending on the head gaskets. Thanks!
