ABORT

Hey I'm new here got myself a ke20 I'm doing up. Just wondering what the exact factory specified weight is for a late 73 ke20, 3k, 4 spd. Looking into engine conversion etc and need to know exact weight to see what engines can legally go in. I have had a good look through google, books etc and asked a few mates and all i can get is roughly 760kg? Any help appreciated Thanks Jon
