Comp LSR lobes - Don Terrill’s Speed-Talk
2020年10月9日 · The LSR-LSL-LXL aren't quite as clattery as some of the previous stuff (XFI-XER, XE) but if its gonna be from Comp, I think the marine, marine high-lift, and HUC lobes are better choices. There is a penalty of some added seat duration, but there definitely quieter and calmer. by CamKing » Mon Oct 12, 2020 6:52 pm.

I have a set of LS3 valves here off a 2010 Camaro that had a well known cam with .64X" intake lift and their springs with 450 lbs of open pressure.

2010年8月31日 · The Comp LSL lobes work well on these engines. Stay away from lobes that are too aggressive. I may sound like and old foagie for saying this, but even the old high lift Marine lobes Comp sells run fast in these engines.
