tunnel ram

IF the OP had some bucks, then a pair of DP's would be in order.
The Carters are mechanical secondary carbs with ether the weighted air velocity door (not a fan) or the spring loaded secondary choke plate (LIKE!) that open up with air demand.

Those AVS's would be pretty OK up top a TR. while not so tuneable next to a Holley, they do well for what they are. Basically, stock replacement carbs.
