camshaft play

[jehusafat]

i have a 1989 f.s.b 4.9l fi i am going to replace the camshaft and noticed that the camshaft has alot of play i can move it in and out about 1/2 an inch maybe a little less than that i was just curiousif it is normal for there to be play or it is just that worn out or if ford did that the only problem i have with it is that it is rubbing against the timing cover. one last thing i was wondering if anyone knew of an easy way to get the camshaft timing gear off i used a puller and all it does is slip off the gear tried it over and over with the same result if i have to cut it off so be it thanks in advance for any help

I have just decided to get a new set a few of the teeth are worn and one is broken.. i had a quick question am i able to remove the camshaft without removing the timing gear and do i have to remove the lifters first

This is the first time doing anything like this and one last question would i be better off getting a stock cam or is there something out there that would not destroy my emissions. i am looking to get a little more out of the engine especially since i use it to tow a boat and trailer
