Exactly. There are things now like more than 2 valves per cylinder, overhead camshafts...Even my diesel is DOHC. The LS 4.8 I cited doesn't have 2...but it will still rape any Grand National motor. Not having a completely modern Fuel Injection system is retarded if you are building a car. Obvious exception is old shit with a carb, but once you go injected use a modern piece.The GN used port injection, so the fuel system is virtually the same. He would have to go stand-alone or adapt (which would be simple given tbe Camaro already has the same system basics) the existing system. Basically a pump/injector/regulator swap, and a good tune.Complete drop in LS with harness and ECU are dirt cheap.The dumb thing here is that in a Turbo motor it isn't the motor that makes power but the Turbo. Comes down to what will run the Turbo more efficientliy and this is where the LS will destroy things. Doesn't suck that if you pop a stock motor you can pick one up for $200. Plenty of guys running stock bottom ends near 1000hp with them. Good luck with a GN motor doing that. That alone tells the whole story. Your argument was that the fuel system is archaic when indeed it's not. While we're at it, the Buick 3.8 architecture has changed very little since the 70s, so even the GN engine could be considered modern. Hell, if you want to argue further, there's nothing advanced about the LS design either. Most all it's technology is old and proven and been in use for decades, so. . I really see no valid points here. His stock harness will almost plug right in, so there's half the battle won. GM used both the 3800 and 3400 in them. I personally would use the Vortec 4.3 if doing a six. You also have to remember your definition of cheap is far different than many others on the board. Not everyone wants an LS swap. Hotrodding encompasses all types. With boost, computer controls, and advancements in materials and machining, it's relatively simple and economical to make big power with anything.
