After the 461 Olds churned out 514 hp and 540 lb-ft with the Holley carb, we decided to experiment by swapping it out for a 750-cfm Quadrajet. The prospect of making loads of power with a super-stealth production-style carb was very appealing. Although the air/fuel ratio was spot-on with the Q-jet in place, the motor lost 50 hp across the board, and peaked 500 rpm sooner. For obvious reasons, we bolted the Holley back on.
