Budget D100 360 Suggestions

The good deal on adjustable rockers would be 273 rockers. Otherwise, stick with the stock stamped ones.

I suspect your dad won't be going to the strip with this... yes? no?. It woudl hlep to know what your dad/you want out of the engine and its planned use: race? mileage? daily driving?. For the cam, I would go lower on duration to keep what little there is of compression with the stock dished pistons. Somewhere in the 205-210 range tops at .050 lift, and make sure the ICL is 4-6 degrees advanced (may be ground in or may not, depending on the exact cam). Keep the lift limited to around .440-.450" so no valvetrain mods are needed. A wider LSA will typically help with fuel mileage; 112 minimum IMHO for this situation.
