Read the last paragraph of my post. This is for a Gen I that has no provision for the OEM roller. Probably the easiest and least cost approach is to locate a pick-up with a provisioned block, many were used with flat tappet cams in them from 1986 through 1995. For 350 roller tappet blocks look for casting numbers 10243880, 14011148, 14088526, and 14093638. There is a block in this period casting number 14101148 this is a flat tappet truck block, its casting number is very similar to 14011148 which is a roller provisioned block. the 880 is the L31 Vortec block but it actually starts to show up in 95 production with a flat tappet cam and the pre L31 steel timing cover.
