Does a rebuilt engine run warm until the break in is finished?

[RJRENTON]

Is the volume in the block equal to the volume in the radiator at all times?

NO...it depends on pump design and pump RPM

[RJRENTON]

No and there is no real basis across the board that it need be.

How did you make that determination??....what is your criteria...or are you just guessing??

How many folks have installed the FlowKooler high volume water pump in a car with a big block and 26" radiator?

440 B/B with Griffin 26" aluminum radiator. FlowKooler pump. I've run Summit's cheapest dual fan set-up as well as the 7 blade Mopar mechanical fan with a shroud at different times. There is no room for a clutch. 180* Robertshaw thermostat. Factory seal at top of radiator to hood. 50/50 coolant mix. 16lb. radiator cap. It did run hotter at break-in but never overheated. Holley Sniper2 EFI allows changing A/F and timing while driving. I live near Sacramento, CA where 100* days are not uncommon and 90s are the norm in the summer. The car runs at 190* most of the time. Cooler days it runs about 180, 105+ days 195-210. I do have a coolant recovery set-up and leave the coolant level in the radiator about 1 1/4" down from the top of the tank. I drive this car almost every day. The car had a 22" radiator originally and I modified the radiator support to expose the whole 26" core.
Over the years I have tried every whiz bang available since I used to dread getting caught in bad traffic or accident delays. A few years ago I reached the current level of cooling and haven't worried about it since. It's a nice feeling.

I have yet to use a Flowkooler brand, it I have used three edelbrocks that have an improved impeller that purports to have the same sort of benefits as Flowkooler. My current 440 car has factory ac and the 26 inches of course. Since this is my third car with the high flow pump, I’m seriously doubting you are being dragged down by your water pump.

You mentioned somebody dumped a can of sealer in the system. If you think it’s not cooling that well, I’d be having that radiator boiled again and also the heater core. That is the only fly in the ointment I can see.

Already have. I posted about it. Maybe in a similar thread.

I saw you had it cleaned. I’m saying do it again and be sure they rod it out this time. It’s really the only stone unturned.

I said it's running cooler somewhere since changing the high flow 180 thermostat to a standard flow 160.

"Running cooler somewhat" ÷ how many degrees???.....5 degrees or 10 degrees or ???? Degrees. Difficult to do calculations without numbers.......or just some more "seat of the pants engineering"?????

You tell me. The ambient temperature went down about 5-10 degrees and the car ran about 5 degrees cooler once I got it up to temperature by driving around with the AC on. Before, the temperature was always about 195-200 flung in gear at a stoplight with the AC on.
