What do you want to do with the car? I'm road racing mine, so the Pontiac 400 was my best option, but your intended use of the car, transmission type etc. can influence which engine you decide to build. All of the Pontiacs 400 and up have the same bore so can technically make the same power as they all have the same airflow. The rest is just picking a stroke and rod length to match your intentions. If you want low rpm grunt, go for a 4.21 or 4.25 stroke, if you want higher rpm power, go for 3.75 stroke and if you want somewhere in the middle, go 4" stroke. Cranks are available in all flavors, so start with a good 400 block and you can have whatever you want. Ideally, a 4" stroke 6.8" rod combo would be what I'd build if starting from scratch...
