I'm getting near the end of my 340 build, and find I need the fittings for my water pump. It's a stock pump. Does anyone know the thread sizes for the bypass hose going to the manifold, and also for the smaller heater hose fitting? Thanks much.
 
Sorry, thought someone more knowledgeable woulda chimed in. 1/2”NPT & 3/4”NPT?. Not real sure.
 
The heater hose nipples are 1/2"NPT and the bypass is 3/4"NPT
