But the LRT was a "Last Hurrah" HotRod and being over 6200 GVW had no emissions in 1978 so a 440 Six Pack would have worked well.
In 1979 EPA slapped Chrysler and made the 1979 LRT have all the emissions.
Washington state use to have SMOG testing every two years. When I'd bring my LRT in and they put it on the rollers and had me bring it to 2500 RPM, the stacks pointing up would set off the Carbon monoxide alarms in the ceiling and they would need to shut down the site and clear the building out. They had to test me outside the building and not on rollers and it passed every time.
