Longer duration on intake camshaft?
I have seen cars with a longer duration intake camshaft than the exhaust side, but it seems to always be in forced induction applications. E.g. DSM 272 intake and 264 exhaust cam.
Now my question is, would a naturally aspirated Beta benefit from a longer duration intake cam than the exhaust cam (stock)
Right now I have 240/240 (two exhaust cams)
Contemplating swapping to 250/240
The 250 duration intake cam comes from a cvvt beta (fits with modification, it's been done before)
It'll be going in a mild p&p Beta2 non cvvt head shaved 0.040.
Thoughts?
