I dunno, I just ignore the motor under the hood when selecting a car.
None of the factory induction systems from the late 70'* through the early 90'* are truely "Great" Some are a bit better than others, but none are truely outstanding. The Tuned Port Injection is the best of the bunch, but even that was a work in progress as GM kept changing the control system. First It'* MAF, then its MAP, then back to MAF for the LT1.
It'* kinda unfair, they are all products from a time where people wanted the big V8, but also wanted cheap gas, low emmisions, and good gas milage. The results are engines with big cumbustion chambers with low compression, very mild cams, restricted induction systems. In other words, performance dogs.
If the need for speed is what you are trying to satisfy, start with a sound chassis. Then start planning the best high power motor you can afford.
