Can you only run a solid cam (roller or flat tappet) in the HR 427? I was told that they do not have provisions for a hydraulic (roller or flat tappet) setup.

Yes the 63 HR's used forged steel cranks (C3AE-6303-V) and capscrew rods in NASCAR. Later in 64 the "7000" rpm kits were available as over the counter items.
Right, the 64 block is a solid lifter only deal and best for flat tappets. Rollers will possibly be an issue. When I bought my Gen block from KC he did a partial restriction and recommends a little
oil to the lifters for solids and solid rollers.
For $6k that's not a bad deal. Nothing wrong with old parts that have been magged and pressure tested.
