Keep us updated too please. I like the swap idea, but would prefer it on a CL500 instead. To me it's kind of a wasted VIN on a non salvage car. The LS guys won't mind, they have no skin in the game. However, if you told them you were thinking of doing an LS swap in a high mileage GNX, they would hunt you down and kill you,LOL. The same suggestion would be made of just using a regular G-body Regal instead of one of the 547. Either way I wish you the best of luck. I think balancing an upgraded rear differential and suspension to handle the speed capabilities will be your biggest challenge. You have shown pics of really clean fabrication on previous builds. Reaching the 1000hp goal is not hard with a little patience, money, time and talent, but it would suck if the car is all over the road in 6 seconds of hard acceleration. Please share the progress here, it's still a W215.
