Sub connectors for 1964 Plymouth Valiant

Whats up guys.

What is the best set of sub connectors for a 1964 Plymouth Valiant ?

I will have 450 hp and close to 500lbft torque. Any reinforcing recommendations?
How do you define "best."

There's nothing wrong with making your own. They'll do the same thing as store-bought connectors at a fraction of the cost.
