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.

2011年3月16日 · LSL lobes aren't as aggressive as some believe and are absolutely fine with stock lifters. With everything setup properly, you should be able to recycle the cam through a few engine builds before it's "worn out".

2010年5月11日 · The lsl is slightly slower off the seat than an xfi, but faster after that. There will be more stress on the valve spring, but nothing crazy like an lsk lobe. The lsl will have better valvetrain stability over the xfi and will make more power. More development went into the lsl lobes than any other lobe in comp's history.

2011年8月29日 · The LSL lobes are supposed to be agressive while maintaining valve train stability. The LSK lobes are higher lift per degree of duration at the expense of valve train stability. Still a lot of LSK cams around, but they are getting harder to find.

2012年5月23日 · The LXL or Extreme RPM for LS1 are good exhaust lobes. I use 231 @ .050" intake duration on a lot of LS3 cars, with at least 11 degree split to exhaust. 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.

2012年5月24日 · Description: These COMP Cams LSR Series hydraulic roller camshafts feature modern lobe profiles that take full advantage of high-flowing late model GM LS3 rectangular port cylinder heads. They are tailored for a specific rpm range …

2013年5月6日 · I like these LSL lobes. Great street cam. Twin Turbo 408 iron block with Comp 68/71 .81 units, custom LJMS Cam, CNC'd LSA heads, custom Sheepey Built 6" core intercooler, homemade fuel system, Flex Fuel'd, McLeod RXT1200 Twin Disk, all assembled and built by me at THE GARAGE.

2011年8月2日 · I'm building a 421 street motor and wanted to see what you guys think for cam options. Heads will be some TFS 220 with mild port work, some pretty good midlift flow. 11.6 CR. All the usual bolt ons, ported Fast 102, kooks 1 3/4 headers, corsa etc. PatG speced 243/247 .627/.632 112+2 with HUC lobes for heavy valves and YT rockers.
