Engine noise-Confuseing

Just built a new 389 for my 66 GTO. It runs great,edelbrock cam.kaufman heads etc.
When I start the motor and only when started I hear a Rattle in the lower end,think thats where it is. only last a mili second then all is fine. I have never had this before in any engine I built and I have built many. It has me confused.
Has anyone had anything like this??
