Save your money, in a Manifold Shootout held some time ago, (in 5.0 Mustang
I think) it was shown that the manifold that gave the engine the most
torque
at the lowest RPM was the one it came with from the factory. I also
remember another article where the goal was to bolt on 85 HP, after
replacing everything that could possibly be replaced the testers were only
a
little more than half the way to their intended goal. They did eventually
reach it but that was after extensive machining of all those brand new
parts. The lesson I took away from that test was that there is about 40
or
more real horsepower still in the stock engine just waiting for you to
massage it out. In the 20 years I've owned my GT the only time it gets
modified is when the stock parts wear out. (I'm just about to roll over
for
the third time, so I'm pretty sure my philosophy is valid).
