And, our old 96 made 444 at the rear wheels with only tubes, filters, high flows, cat back and 98+ stock headers. Also made 504 RWTQ. My red, white and blue car last dyno'd at 435 RWHP with the same mods.

Earlier cars responded VERY WELL to freeing up the exhaust side of things.

If you can live without ABS, that's why those cars are so desirable, IMO. cheap HP increases.
