TPI is Tuned Port Injection.

Go TBI (throttle body) it's cheaper, simpler to install, easier to find and will work just as well for your application.

Another really easy, dependable mod is a serpentine belt set up, well worth putting in.

Feel good about the 14BFF, it's totally on par with the D/60.
