Welcome to the forum. That's a solid looking Regal you found. It may be rare but like you already know, it's not fast and it would take a lot of resources to make it a real performer. An LS engine will definitely wake this old car up. If you plan on driving it a lot though I would recommend going with an overdrive transmission. Take it from a guy who drives a Monte Carlo with a TH350. Overdrive makes longer drives much better. If you want the strength of the TH400, a 4L80E is basically the overdrive equivalent. Any idea which LS engine you're gonna use? Definitely keep us updated with your progress. Consider starting a build thread when you get started. Good luck on your project.
