you guys are confusing the OP's numbers. The LSA is 112 not the ICL.

If all the manufacturing tolerances are correct for the cam, dowel, sprockets, chain, crank keyway.... The ICL would be 108º BUT without seeing the raw cam card numbers who knows.

IMHO no camshaft should ever be put in without a degree wheel.

I think cam companies recommend the 4º advance is because the vehicle is always heavier than thought, has less compression, less stall, less gear, etc. They've adjusted for end user optimism




I agree that you see alot of people confuse the Lobe Seperation Angle (LSA) with the Installed Centerline (ICL) and get the cam in wrong. But you should always degree the cam as just manufactors tolorances can have it off some and unless you degree it you will never know where it really is and if your leaving some performance on the table.
