Stroker specific cams?

Just saying- I have to read the posts
but
LCA is a RESULT not an INPUT
get your Intake and exhaust seat open and closed points and LSA and overlap just magically appear
IMHO overlap needs close watching with EFI
if the overlap and LCA look wrong when the results are in take another look
then note what the .050 numbers are so you can time the cam
If solid we are adjusting seat timing for lash

Exactly. The LSA is a result of event timing. You can fudge a bit...maybe 2 degrees but after that, you are changing the timing.

That's why I say the events have to be correct. And lobe aggressiveness in most cases is important if you know what you want.

Usually when the LSA looks wide to me, you can see the duration is too little for the displacement/RPM/induction/application and you end up moving the timing around. Like I said...that's why the big duration splits almost always end up with a wider than needed LSA...to extend the RPM range because of lack of duration.
