Carbureted versions of the 5.0-liter small-block V8 were still available, but the big improvement came with the fitment of Tuned Port Injection (TPI) to that engine to produce a flexible 215
horsepower. Sadly, the TPI engine could only be had with the four-speed automatic (in either the IROC or the regular Z28).
