Hughes engines offer Johnson hi lift lifters. There fine for use and can be gotten cheaper else where.
Depending on the weight of the car, that cam will like a RPM AG, a 750 carb and a 4.10 gear on 26 inch tires.Your converter is OK for use. It maybe a bit high, but it’s a LOT better than being to low. I’d run it.
Run a trans cooler.
