How big of a pain in the butt is it to replace on the 472?

to do it right you have to drop the oil pan. this way you can seal up the timing case cover without any leaks.. and when the pan is off you can clean out the oil pick-up tube. it will be loaded with little plastic pieces from the gear and valve seals...BE CAREFUL don't mix up the bolts from the pick-up tube and the timing gear.. they are almost the same but the tube bolts are longer and will hit the block..Only use a good roller chain with the steel sprockets.. they start at about $80..If you are keeping the stock cam use the +4 degree keyway on the new gear..I'll give you more info if you do it..

I would PM you but you don't have enough posts to recieve one.. Before you drop the pan I would drop the Y pipe and unbolt the motor mounts, thats from the bottom.. Thats so you can jack up the motor to get the pan off...
