Picture 1 of 6 from Album parts i dont know for sure what year they are
timing chain covers and pullys. 455 left. 400 right. i must have tossed the 400's balancer. so i am left with the 455's. notice that the 455 balancer when placed in the 400 cover will completely cover the timing marks, so the 400's balancer must have been much smaller diameter.
