[Tigers] cam exchange

[Gary]

Tym,
 
You do not need to remove the heads, just the intake manifold and valve
covers, so you can backoff the rockers and remove the pushrods and lifters.
Make sure you do that before you try to remove the cam. Quite often the
bottoms of the lifters are mushroomed from wear and they will not come out the
top of the lifter bore. With the pushrods removed and timing chain off, rotate
the cam, so each lifter comes up to the top and then try to remove it without
scraping the sides of the lifter. A scratched lifter could damage the lifter
bore, if they have to go out the bottom. If a lifter will not come out the
top, leave it at the top position out of the way of the cam lobes until you
remove the cam and then push them out the bottom, granted you will have to
take off your oil pan, if you haven't done so already.
 
Good luck and let us know how it goes.
 
Gary
