[427king]

I took a 20K mile 67z motor with original bearings apart 3 /4 years ago and it had a 6467 crank. Ive always been under the assumption that everyone used the 283 crank because there are 20000 of them for each 6467 you will find? I dont usually go solely by what is printed in a book ,but ive always seen 6467 listed as the true Z crank for 67 in most publications. I guess its like using a 6223 crank in an L88 instead of a 7115. Why spend 1700.00 when you can get the 6223 for 250.00,and some people will argue both are correct ??
