T.T.I's vs. ........you be the judge

No, Rumblefish... it is in no way an attack on you! There just seem to be a lot of folks that don't think the "standard" tti's would do well on an engine over 300 horses.

According to what Mr. Arrington told me, The tti 1 5/8 to 1 7/8 stepped headers pull equal or better horsepower and torque numbers through the entire rpm range from idle - 9500 rpm. They are equal to the bigger tube headers on the top end from 6500 rpm and up. But the throttle response and acceleration numbers are superior up to 6800 rpm.

Of course, I will have to see for myself once I get the stuff into my car. But coming from someone that has done this for a living for a whole lot of years... I will take him at his word.

Someone else asked what he was doing to the engine. He took my 74 360 block and reworked it basically into a race block with a Jesel roller valvetrain. Then he made a pair of one off heads from castings and prepared a matching Wilson intake manifold. I am waiting to see the dyno sheets and flow numbers! It will basically be a "detuned" NASCAR/Sprint Car engine. The beauty of it is that it is supposed to run fine on pump gas.
