I also can't tell from your photo but are those bolts you are using to hold the cam thrust plate to the block instead of screws? It should be held in place with a pair of pan head phillips screws and internal star washers. Also, you are using the thrust plate and the spacer ring correct? So if you are using bolts and the cam gear is catching the bolts, switch over to the pan head screws. If you are using the correct screws, and the thrust plate and spacer, I wonder if you installed the rear cam plug in too deeply and when you are tightening the thrust plate, it is causing the rear cam journal to compress against the rear cam plug?

That plug is very shallow because the camshaft comes close to it.Some vendors sell a plug that is much too deep. If one of those was installed, the camshaft would bind on it. | | | | | Joined: Jul 2007 Posts: 444 Shop Shark | | Shop Shark Joined: Jul 2007 Posts: 444 | Camshaft Thrust Bearing Screws are available from Chevy of the 40's for $1.50 . https://s26.postimg.cc/t26503vmh/Chevy_Parts_Camshaft_Thrust_Bearing_SCREWS.jpgCamshaft Bearing Hole Plug Early Models Chev. 1937 to 1954 - ( with small journal camshaft ) GM # 0.553 - GM # 838127 - Diameter 2 " inches GM # 838127 is available GM NOS @ Collectors Auto Blaine, WA. phone: 800 - 414 - 4462 Collectors Auto has ( 3 ) in stock 1954 / '55 / '56 / '57 Chev. 6 cyl.
