HELP!

So engine has to be up....?
Not sure exactly what You mean by "up", but usually I try to pull the cam w/the eng on TDC#1, once it's ready to pull. As zkx14 said, the dizzy,oil pump, fuel pump,& lifters all
have to come out 1st, there is no pushrod for anything but the 12 rocker arms, 1 a piece,lol! Depending on the vehicle, the rad. & grille may both have to come out, and it's a
little tricky pulling it all the way w/o nicking the bearings w/the lobes. Get a long bolt w/a sleeve on it the same thread as the cam bolt, & use it to help control the process.
