1978-1987 Buick Regal - LS Swap

In terms of pure performance, the Buick Regal probably doesn't rank highly on most people's lists. However, it was built on the versatile G-Body platform, allowing various engine swaps and a litany of performance parts to bolt right in. This includes bolting in Gen III/IV LS engines, and we'll show you what you need below.
