Lift is a bit high for a stock rocker and a bit too much overlap for a stock converter. In theory you could likely just change the camshaft and possibly the pushrods.
Well I was told also that it has new ls7 lifters installed. I'm not trying to pull the heads to change lifters if those are good. The valvetrain is surprisingly quiet. I am also going to remove valve cover this weekend and see if they changed the rockers, what I've seen from the video from 187 customs they just did the trunion kit. I don't know what length pushrods are installed, so would prob order a replacement set of those if I did the cam.Just get a cam install kit. Also get a new timing set and lifters and push rods. Plus all necessary gaskets
We have a number of options for cams that will drive nicer then what you have now with a safer level of lift for stock rockers.Well I was told also that it has new ls7 lifters installed.

Also in support of your statement above Matt; net valve lifts of over ~0.600" do not work well with either stock heads, or many so called ported heads. It takes a well ported head to flow at or around 0.625" of valve lift.We have a number of options for cams that will drive nicer then what you have now with a safer level of lift for stock rockers.
