[QUOTE="50 BMG, post: 2952875, member: 16523"] Wherever this came from... LS1 fully dressed weighs about 497 pounds. LS7 will weigh at least the same and probably more with the dry sump system. [url]http://www.ls1tech.com/forums/showthread.php?t=347900&highlight=LS7+weight[/url] McLaren F1 engine weighs 266kilos inside the car in operating condition, or about 540 pounds. As far as which is more compact, thats more of an "in person" thing. I've seen 6.0L the DOHC in both the Enzo and the McLaren. If they're bigger in terms of physical size vs. the LS7, you'd have to bust out some rulers and have the engines out of the car to truly find out. F1 engine is still way better. It makes the same torque as the LS7 with only 370 cubes while also making over 100 more horsepower. It has a compresion ratio of 10.5:1, while the LS7 has 11.0:1. I lost the cam spec on the McLaren's cams, but IIRC they have less overall lift than the stock LS7 cam which is .591.
