That 292 is just begging for a Rochester Quadrajet calibrated for a Chevy 305 or an Olds 307 engine. It has tiny primary barrels with a 3-step venturi, and a secondary air valve that prevents overcarburetion when those huge secondary throttle plates open up. The "small" Q-Jet has a 750 CFM rating, yet there are no flat spots from idle to all the CFM the engine can flow. I ran a 460 cubic inch truck pull engine based on a MOPAR 440, running a QJ for a 455 Buick. It dynoed at 714 HP at 6500 RPM on one carb and aviation gasoline. The carb would let it wind to 7500 RPM or more, but the torque started dropping off at that speed.
