The Stovebolt Site Forums The Shop Area The HiPo Shop How much coolant?

Just finished putting my new motor in. This motor is a 430hp 350 (V8). My questions is how much coolant should it take? I have heard 5 gallons, four gallons, etc. When I went to fill her up, it only took in 3 1/2 gallons. With the block, water pump, and everything being bone dry, I wonder if that is enough. I have start it up a couple of times and re-topped it, but it has only dropped slightly. Heater core, and all hoses get warm, so I do have flow. Don't want to run it for too long until I'm sure that is has all the coolant it needs. Thanks.

I would figure about 4 gallons but if the hoses are all hot & the radiator is full, thats it. You can remove the outlet heater hose to vent it but you wont find any air in it.

Thanks for the reply. This newby mechanic just doesn't want anything to go bad on him. I'm into this far enough that if something went catostrophic I'd have to postal or something.

Hope to have a video up in a day or two for those who would like to hear the new motor.
