273 Camshaft Specifications
Thanks for the cam information....likely go with the Isky option. I'm curious that two Isky cams are mentioned in the posts. 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'.
