anyone ever mixed up rod caps??

I think I can top all dat. In my Ford days I just installed a 351 Cleveland in my 72 Ranchero, was about to crank it up when my spagetti eating fat Italian brother in law pointed at the torque convertor, (on the shop floor) And said "donna ya haf to putta dat in da car first?" God rest his soul, I miss that fat^%$&*@.
