I'm finally attending my new engine for for my cobra. I was putting the new Ford secondary chains on and found that in order to get the chain on the passenger head, I have to loosen the cam caps on one cam, put the chain and sprockets on and tighten it back down. It seems way too tight to me, but I can't figure how it could be wrong. The chains are factory ford replacements. Does anyone have any ideas or thoughts on this? Thanks in advance!
