Webers with thermostat???
This is directed to those of you with 289/302 with 48 IDA's using a manifold with the dual water outlets (forward facing), ie without the thermostat housing integral in the manifold.
The bypass hose is eliminated when this type manifold is used, there is no bypass. Is it intended to be run exclusively without a thermostat? I have tried putting a smaller thermostat with a couple of holes drilled inside the hose but have blown a hole in the new upper hose once and blew the hose off the connecting tube another time. Are those of you that have this type manifold running without a thermostat? Are you using some sort of in-line restrictor? I want to keep heat in the motor but am reluctant to operate without a thermostat . What are your experiences? What temps are you able to maintain? Operating temps dropped about 5-10 degrees with the Webers.
I have seen some bushing type resrictors that fit into the radiator necks, anyone using something like that?
