I'm running an aluminum griffin radiator and a typical waterpump set-up on my 347. I want to run some stainless braided hose for my upper & lower hoses. I have the 20an fittings and the hose for the set-up. My issue is that the thermostat housing (waterneck) is cast iron. Aluminum and iron+dissimilar metals...ie, can't weld the fittings on them. Does anyone make a aluminum thermostat housing or can some type of modification be done somehow.
Thx
