At a race weight of 3770 for the '92, it looks like it would take about 325 horsepower or so from a truck 5.8EFI, just to make the 13.15 O/SA index. And that's a lot of air to push at 100 mph or so. The stock heads are pretty horrific on those things, especially the exhaust port, and I don't see any replacement heads listed for the Stock classes.
