Re: Water pump ID
Before 1969, Camaros had "short" water pumps. They switched to the long pump in 69 and the alternator moved from the driver's side to the passenger side.
I guess they sold you a "short" water pump for a 1968 Camaro; but you need a "long" water pump for a 1973 350 engine.
Just tell them you need a water pump for a 1969 Camaro and it should look like the one that's on your 1973 engine.
68 Camaro convertible, 6.0 LQ4 with LS3 heads, Vintage Air, 750 street demon carb, eddy perf rpm, GM hot cam, Hooker headers, 4L80e, 12 bolt, 3.55 gears
