I just looked at my cam card and it says the lobe separation is 104 int./ 112 ex. How well with that work with NOS ? I would like to spray mine and make a 5.99 or better 1/8 mile pass.

A cam only has one LSA, that is ground when it's made. The LSA is degrees between intake and exhaust centerlines in crank degrees.
Wider kills low end torque and bleeds off effective compression, but makes more high rpm horsepower

LSA is in Cam degrees ILC is in Crank degrees. The numbers D50 posted are ILC in crank degrees. His cam has a 108 LSA and is installed 4* advanced giving him those numbers of ILC
