That's what I was gunna do tomorrow was take the water pump back cause I know it's a reverse flow pump on those 350s but no temp gauge reads fine I let it idle for thirty minutes minutes no problom but like I said when u hit the gas peddle I can feel the resistance then I floor it and pop there goes the gaskets it's weird as fuck man Iv been working on cars for 4 years now and have seen a lot but have never been stumped like this it's odd as fuck I'm gunna pressure test cooling system tomorrow but am not sure if that's my problom I shouldn't feel it in my gas peddle this all happened a couple months ago I just started working on it again these past two weeks there was a loud pop when this all started happening then a couple miles down the road pump blood up not be gaskets it just streight blow up through the shaft so replaced it and ever since its been doing this like I said I did head gaskets this weekend so I know my problom is else wear
