TPI was designed for lots of low end torque not top end.

If you are going to stay stock or mildly modified I perfer TBI in a truck for its simplicity and lower cost.
Both TBI and TPI build good torque.
If you are going to modify the engine with a hotter Cam and more air flow then I would go with TPI. Because they are Mass Air flow based system they tolerate engine mods better than TBI systems.

Sounds like a great reason to put the TPI on the 350, and have the best of both worlds. /forums/images/graemlins/smile.gif
TPI as it came from the factory was not a high RPM powerhouse. The long runners limit upper end horsepower, but torque is very impressive.
