Sticking with the theme of LS swaps, the first guy who did it successfully must be dead by now because even with all the swap-friendly stuff you can just buy now had to be fabricated for sure back then. And tons of trial and error and a lot of frustration and work. And MONEY. Which even with the off-the-shelf parts, the swap is still rather pricey. And then you have this lump of numbness in between the wheel wells. I mean, the thing is, I'm sure seeing the first few pioneers do it, everyone was like, "wow". Now, it's so mundane nobody even looks at them at car shows anymore with the same sense of awesomeness. Even GM got in on making swap kits virtually plug n play. It's still cool, but it's yesterday's news.
In fact, if you have the original engine in an older G-body, people are slightly amazed. I see a turbo LS and to borrow a phrase from Fry-me-a-burger's article, like, yeah. Whatevs. The crazy part about all LS engines is that GM built them conservatively, and the identified flaws notwithstanding, they leave a lot of potential power on the table when they left the factory. There's more power in them thar engines! And it's not tough or super-expensive to extract it. Just the mere addition of headers and a freer flowing intake and exhaust system can really start to wake one up. Cam heads and power adders on top of that can really make them scream. An LS in all flavors. Fun for every price range.
I have 3 LS engined vehicles. All 6.2L in various HP configurations. If I get the hankerin' to have some fun with LS power, I just hop in one of those. My Oldsmobiles, however, will never have anything but 10 or 5 bolt stamped steel Olds V8 valve covers on them. Why? Because I can. Run with whatever flips up your skirt. Just as long as your having fun yanking on wrenches, that's what it's all about.
