My "HOLLY Bible" sez the 4777 is a; Model 4150, double pump, mechanical secondaries, dual feed/center hung float bowls, manual choke, and is a 650 CFM. Designed for off/road performance or street use. Non-emission. The 1850 is a; Model 4160, Universal calibration (1964 and Earlier) Manual choke, single feed/side hung float bowls, vacuum secondaries and is a 600 CFM. And you can use these carbs in 49 of the 50 states. Guess which is #50.
