Unsure I have a freshly rebuilt 351C, car is a 1971 Torino GT. It starts and runs perfectly. I let it run for about fifteen minutes while adjusting carb, checking timing. When I turn it off it keeps making a popping sound right at the thermostat, like its opening and clossing hard,(and fast, but not regular interval repetition) I replaced thermostat thinking that the parts store sold me a bad one, does the same thing. Swapped the waterpump also. No difference. I ran it without thermostat to make sure that it was pumping water, and it is, Also have a brand new aluminum radiator. The thing that bothers me is that the noise sounds mechanical, but doesn’t start until the water heats up. There's no EGR reactor valve to cause such a problem. All parts in engine replaced brand new. None of this happened prior to rebuilding, what could be wrong? Leak somewhere that I can't find? Vacuum problem somewhere? Sratching my head here. I would really appreciate any direction you guys could offer. Thanks ! Jim

do you have the stock t-stat housing or one of the chrome replacement ones???

ive heard nothing but bad things about the chrome replacement ones. from leaking, poor fit, poor craftsmanship.

if you have one of these im thinking your problem is the T-stat is getting hung up on the housing.

I forget - sorry, but does this use a metal pan under the intake manifold somewhere? Could that be reacting like a pan on a stove with heat and cool down as this does this with engine off - right? With all the parts replaced is there any chance a washer or something is just setting somewhere loose and flips around but hasn't moved like a coin flipping?

Since this does this with engine off I think I'd remove the intake manifold and take a look around??

Who knows?
