Description: Old model 4777 made in 1974 (0304 date code). Two-corner idle main body; hasn't been modified. See below for gaged specs. Uses same 1-11/16 bore throttle body (base plate) as 700, 750, and 800 double pumpers and interchanges with those main bodies. Complete or build your own 4777, wrap in new cast or billet blocks, however you want, and let it rip!
