Thanks everyone, for all your reply's. I'm trying to find out more info at the moment, as I mentioned the replacement crane cam & lifters were sourced by a friend of mine quite a few years ago.I don't have any paper work for it,but the cam was to be just a like for like replacement for the original/stock one. the cam looks like it would be ok if it was spaced about 2mm forward, almost as if there is a spacer missing from behind the cam sprocket and the block.But all the info I can find is that the sprocket runs directly against the block.....
many thanks again to everyone who is trying to help.

Check the cam bearing boss to value cover distance block could have been machined for a Torrington bearing setup
Or repaired to except a hardened shim.block may have been slightly damaged at one point in its life

Crane roller cam upgrade was popular mod on a 30k motor that ran a relatively lame cam . I do believe that involved a torrington bearing . thats alot of cid valvetrain mass and potential spring pressure for a flat tappet these days . Even back in the day .
i think the orig hp575 based 540 ran solid at one time
