Can anybody tell me the Lift, Duration, LSA @ 50* on the stock cams that come in the 35/ 36 Briggs?

Max Lift
Intake .363 Exhaust .357
Duration
Intake 205.8 Exhaust 210.8

Any clue what lift the springs are rated for and what about LSA?

You're trying to equate these to HD cams and it just doesn't work.. No idea was LSA is or valve timing.. The info Mitch posted is exactly what I got back from Briggs when they profiled another cam against the stock cam.. Even when I had Crane do a custom grind for me they never listed LSA but they did list duration of the final grind.. Stock springs are somewhere around 20# give or take.. The double wounds are around 30-32#.. My cam is about .483 lift w/ roller rockers and with the double coils I never had a bind issue.. Gonna go back to stock rockers and shimmed stock springs and see if they bind when I put it back together next week..

Good info, at least you got a response Brad. I posted an exact thread about this a few months ago and No bueno.

LSA should be somewhat easy to find if you have a jig setup to find the highest point on each lobe and measure the LSA from there. LSA= Lobe Separation Angle for those who do not know!
