Hi! Had a cam bearing failure in my Indy aluminum block. It went so bad that the block actually have melted a little in the #3 and 4 cam bearing bores, so just can't install new bearings. Others are ok. You can't get it welded either, no room for that.
So, does someone make needle bearing cams (and bearings) for a bigblock? It could be one solution to drill the cam tunnel bigger for roller bearings.
