Anyone running a original 40 Ford Flathead in your hot rod? Were do you plumb the hoses on the engine? We are trying to figure all this out while detailing the engine so everything will be in place before the engine goes back in Dave's confused 32/34 pickup. Photo's would help. HRP
I don't have a definitive answer but I do recall removing heater hose fittings from the heads on my "32 pu w/46 truck engine. I'd have to go to an old Ford book to figure it out.
On the Ford Barn there is a guy 40larry who does 39/40 Ford heaters he will have installation instructions his name is Larry Kaplan from Ca.

Just for your info the original 1940 vehicle installation used a nipple installed in the lower radiator hose. The early Ford suppliers carry them. Charlie Stephens
