Have you built a motor before?
Look at the back of the block. There's a large frost plug covering the back of the cam tunnel. Above the cam, are there 3 holes with pipe plugs or small frost plugs, one on top, one at 10:00 & one at 2:00? If you have the holes plugged at 10:00 & 2:00, you can probably run a hydraulic cam. I was wrong once before, but to my knowledge all 428s were drilled for hydraulic lifters.
