go with Jim at racer brown or Bullet or Jones or most anything except old E-4 and 340 cam
you leave HP on the table with the E-4 and torque with the 340 (and HP)
Yep, it all depends on what you are doing. If you just need a stock replacement and don't care much about performance the E4 works well. There's always something out there that is better or more powerful.
