E-cam vs B-cam?

[eatsgmcar]

The cam is not a part that will give 25 more HP. It will
give from 12 to 20 Hp more. Then when you swap the B
(+12 Hp*** over stock) to an E (+16 Hp*** over stock) you wont
see a huge difference but why choosing the worse when
both are at the same price?

***Per the MM&FF dyno session

I totaly agree that the cam could cause idle problem. However
when the car dies all the time and the idle is always surging
every time the engine is around 900 RPM. It is too easy to say
that the cam is responsible. When the problems are major
it can t be the cam alone....
