RE: B303 OR E303
There was just a post on this yesterday...my take is that the E303 is a milder cam but will pass emissions. Ford sells crate 5.0's either with E or B cam and they quote the hp of the E cam as 5 less. They also say to use the E with an auto trans.

RE: B303 OR E303
I have the crate engine with the ecam. I like this cam much better for street. The B cam's idle is pretty lopey because its powerband starts at 3200rpms. The Ecam starts at 2-2500rpms. Plus, 5hp is hardly noticable.
