just fitted an LT1 in my willys and need to spec a cooling system, what do I do different as it is reverse flow cooling cheers

Nothing terribly exciting. Use a stock rad, and run the vent hose from the back of the cylinder heads somewhere into the upper radiator hose, if memory serves me rightly.

you need a reverse flow water pump if the motor isn't already so equipped. i know someone who has one for sale, pm me if you're interested.

Need an LT1 specific water pump. Inlet/Outlet ports are different.

thanks, came ready to run but guy i bought it off said be careful as it was reverse flow but he couldnt really explain what difference it made to cooling system

nothing different from normal as i remember, just make sure all air is bled out. Do like big Angry said and vent the back of the heads back into to keep air from circulating.
