TR-5 Tunnel Ram

A progressive set up activates the rear carb first and then the front carb second. The opening rates are different so they end up wide open together.

The inline bar opens both up at the same time. Edelbrocks progressive set up can be done booth ways. When both carbs have the same opening rates, the throttle response is very strong, made torque. The progressive set up is softer off idle with a explosive feel when you get up top or closer to wide open throttle due to the front car. Opening faster to catch up.

For a T-ram. I suggest a 1-1 or direct linkage set up, both at the same time.
