Hello
I have just finished my ls1 conversion and i also weighed my old engine (2 bathroom scales) but it was a 2,4T engine with magnesium engine case but it weighed just 400 lbs (195kg) and the new ls1 was around 430 lbs + exhaust = 450 lbs. But with front radiator i think the balance still is good maybe even better than before. Have a nice day
And here is a picture of the finished projekt
