One of my best friends at work, her boyfriend has a Stag, I love the T-bar top arrangment. I've always thought they were really nice cars, nice back seat for hauling the kids around to car shows and whatnot. His has the original motor still in, and a manual trans. From what I understand the original V8 was a bit of a nightmare, he had a heck of a time getting the heads off when he did the rebuild. Engine issues seem to be the reason why there are so many conversions, although most I see are Buick V6's or SBC V8's. His goes like a freight train, I will say that. Rust seems to be a big issue with those cars as well, but then again what LBC doesn't have that problem. Well, can you really call a Stag an LBC? Maybe MBC (medium-sized British car). If the body is in good shape and the conversion was well done and a clean install I'd say go for it, unless the originality is a big factor for you.
