I agree with you guys about the 351 build but if he already has the 302 block and is set on using it, why not a clevor?
You know when Bob Glidden won the world chapionship in 73 with a 351C he had de - stroked it to a about 330 ci. motor.
So if this is going in a light car, I would say a stroked 302 is a good way to go.
You can wind the piss out of them and if you got a good bottom end you'll never have to worry about breaking it.
