what solid cam is equivalent to a hyd 268 ?

If I go to this isky e-4 solid I think it is just a little too whimpy for my taste "daily driver friendly" . How about a step up to a E-3. see attachment >>>>>>>>>>>>>
What is the difference between an E3 and E4?
Also, the Isky and Summit websites are the most non-intuitive (frustrating to say the least) when searching for answers. Any suggestions on the best place to buy an Isky cam kit?

Thanks again..FABO is the place.

The 'E-3' makes a little more grunt on the 'Bottom-End' and 'Mid-Range'.

But it is like 'Night-and-Day over 4500 RPM's, as the 'E-3' makes some
very good upper Mid-Range power.

The Iskenderian 'E-3' Camshaft was called 'The Original 3/4 Race Camshaft'.
