Just one question. How much weight is there between the stock 6 and LS conversion and the weight bias? Sorry engineer first gear-head second with a love of power to weight ratio. I have been thinking of this engine swap for a while and I like to do my homework before I commit and remove a thick wad of cash out of my pocket.🙂
Check out this video ... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eWxINKZj0a0.html at about 5:45, she puts an LS3 (aluminum block) with a GM 6 speed on the scale compared to BMW running gear and the LS is only 15lbs heavier than the BMW stuff!!!
OHV vs DOHC engine, no VANOS, aluminum block and head...you can do an LS swap (with an aluminum block) into anything and it'll be close to the stock weight of whatever engine you take out.
