ok guys ran into a snag. i lined all of the timing marks up. while i was cranking the block over by hand it stopped about half way around. this tells me that i have a piston hitting a valve. now heres my question. is there anyway to time the cams without having to go spend a crap load of money on a tool?? any help will be greatly appreciated. this is keeping me from dropping my motor back into my car. thanks guys.
