In car cam swap

Do the cam, water pump and timing chain all at once since you are in there.
I did a in-car cam swap on an neighbor's FHP car when he was on vacation.
Out with the smoger cam, in with the fun cam. Really woke the 440 up and his Lt. never knew it. Later on the Lt. rode with him and commented on how lively it seemed. Neighbor replied that it was always like that and must have been built with all the production tolerences stacked on the good side.
