Well.. I dyno'd the Cobra the first of the week. There's good and bad.. I'll talk about the good first. I gained around 70 rwhp by going from the Spiral Turbo inserts to the 3" Chambered Exhaust inserts, no other change. Temperatures were similar (within 5 degrees) and the same dyno was used. I dyno'd 370 with the Spirals and 440 with the Classics. Kudo's to Eric @ Classic Chamber for providing a quality product and the customer service to back it up!

Now for the bad... Even at 440 rwhp the motor's developing much less than it should. I can only assume that it due to my restrictive heads. I had Keith supply me with valves and springs but I had a local shop accomplish the port job and assembly on a set of Eboks that I already had. The port work looks great but I honestly believe that they flow no where near Keith's stage 2 or 3s.. There's just no other logical explantion. Now ..... do I want to spend another $3K for a set of stage 3 heads or just accept what I have now??
